Cisco Firewall :: High Memory Utilization On ASA 5510

Sep 13, 2012

We recently added about 400 users to our network for a total of 1000.  Looking at the ASDM we are holding very tight to 75% utilization and we have 256mbs.  This is also running IOS 8.2(1).  Our firewall recently crashed after a major download was forced through it.  This was after only being booted up for about a week.  We had reloaded it a week prior after having ran it for about a year without issue.  We havent made any changes in the last month other than adding more users to our network.

Cisco Firewall :: Very High Memory Utilization In PIX 515e?

Feb 15, 2012

We had two PIXes in our environment and working as a active-failover mode. Its noted in now a days the active PIX memory utilization is 98% and for standby PIX it is 96%. And also in some times we were experiencing packet loss to the ip of active PIX and which reflects in the inside servers access also. During that time the active pix was not accessible via ssh as well as ASDM. We have tried reloading the PIX and changing failover state of the PIX, but it results only a temporary solution. Current memory installed is 128 MB (maximum upgraded), so a upgrade is also not possible. Please see the show command outputs from the PIX. Current Software version is 7.2(4)
 
sh memory output (PIX 1 - active)
 Free memory:         4850944 bytes ( 4%)
Used memory:       129366784 bytes (96%)

[code]....
 
1) How we can pin point the root cause of this high memory utilization?

2) What might be the reason for the high memory utilization for the standby pix (96%), still the PIX is in idle state?

3) Is it a hardware issue or a memory leak issue, then how can we find out?

4) Is a software upgrade to new version resolves the memory issue?

Cisco WAN :: High Memory Utilization In 7206 Router

Jul 29, 2012

We have a 7206 router which acts as a MPLS Hub router for around 100+ remote locations. Bandwidh at mpls hub(terminated on this router) is 50 Mbps.
 
We have noticed that Memory utilization in this router gradually increases and when it reaches 100% this router hangs. It happence in frequesncy of 10 days and we have to restart the router when memory is 100%.
 
CPU utilization is normal i.e below 20%, WAN bandwidth will never cross 30mbps.
 
We are running OSPF on this router

Cisco Infrastructure :: 2960 - High I / O Memory Utilization

Oct 26, 2011

We recently installed two 2960, both of them with this fw version:

Cisco IOS Software, C2960S Software (C2960S-UNIVERSALK9-M), Version 12.2(55)SE3, RELEASE SOFTWARE (fc1)
 
The switches see very few traffic (under 40MB on all interfaces, summed, so far), however, I/O memory utilization is about 80% as can be seen from the show memory command:
 
Head    Total(b)     Used(b)     Free(b)   Lowest(b)  Largest(b)
Processor    2B89A18    73969000    27198964    46770036    45060368    29367536
      I/O    6200000    14680064    12185292     2494772     2323116     2380896
Driver te   1A00000     1048576          44     1048532     1048532     1048532
 
The memory allocated is almost all Packet Data, by init, "sho memory io dead" returns  zero, the memory usage seems constant, there are no errors on the log, the switches operate correctly, no packet has ever been dropped, CPU usage is about 4%.
 
Here I showed info for one switch, the other is in the same situation. I just want to know if this behavior is expected, I don't want to find out problems when the switches will be in production whit real traffic.

Cisco :: High Memory Utilization After Few Days - Ciscoworks LMS 4.0.1

Sep 18, 2011

I have the problem that our ciscoworks server gets out of memory after few days. The memory utilization is always getting higher an higher (above 95%). Sometimes it is only after 3 days and sometimes it is after 1 week. So it happens not regularly. I have made an screenshot from the services which use a lot of memory. And at this time the memory utilization is getting higher and higher again....I think there is a problem with tomcat or dbsrv10.exe, there are also a lot of cwjava.exe running.

Cisco Switching/Routing :: 2960 High Memory Utilization

May 2, 2013

I noticed on the 2960 switches we have deployed that are running the latest IOS, 12.2(58)SE2, memory utilization is really high (almost 80 percent). I have not noticed any side effects but I wanted to verify this is acceptable. My question is does the high memory utilization matter? I see this may be related to bug CSCtw83946 but no resolution is mentioned.
 
I did some testing various IOS revisions and below is what I have found using a WS-C2960-48TC-L with default configuration and only my laptop connected to a switchport in vlan1. You will notice memory utilization will grows with each version but jumps drastically with 58. One difference with 58 I needed to use a different command to retrieve memory utilization. The output was gathered by pasting the output of the show command into the Cisco Output Interpreter on their website.

Output
c2960-lanbasek9-mz.122-35.SE5.bin

Cisco Switching/Routing :: 3750g And 3750x High Memory Utilization?

Jun 11, 2013

We had a stack of 4 qty 3750g running IP base on ver 12.2.32, then installed a 3750x to the stack and upgraded the whole stack to 15.0.2 SE3. In doing so, we noticed that the memory utilization jumped from 60-70% to 83-84%.
 
We had the same issue occur when upgrading to 15.0.2 SE3 on another stack that was 6 qty 3750g running ip-services, but this one jumped to 90%.  On the 6 qty stack, we downgraded to 12.2.55 and the memory util went back down to 60-70%. 
 
On the mixed stack, we replaced the 3750x with another 3750g and downgraded the whole stack to 12.2.55, however, the memory utilization did not drop down.  As far as I can tell, no config changes have changed from the original IOS.

Cisco Firewall :: High CPU Utilization On ASA 5550?

Mar 10, 2013

I have Active Standby ASA5550 setup with VPN premium license. A few days back we had a requirement of SSL VPN connection for and we got a temporary from Cisco for same, this license expired and the ASA reverted to it's original license. 3 4 days after this we saw a sudden increase in CPU utilization (upto 90% + -5%) on the ASA during production hours but were not able to figure out the reason, in order to restore the services we failovered the firewall to secondary and everything worked fine. We were suspecting one of the following but there were no logs for any of this
 
1. The ASA hardware was haivng problem

2. Some client was doing a DoS attack to bring down the ASA (no logs for this as well).
 
We took a downtime to look further by failovering the ASA back to primary and it worked fine without any issues ruling out the 1st option. We also came across a licesing doc [URL]
  
Downgrading any license (for example, going from 10 contexts to 2 contexts).
 
# Note If  a temporary license expires, and the permanent license is a downgrade,  then you do not need to immediately reload the security appliance; the  next time you reload, the permanent license is restored.
  
As per this doc, sooner or later a restart was required on the ASA. We restarted secondary ASA and everthing was fine but when we restarted the primary ASA by swtiching over to secondary some of the server (not all) in the DMZ stopped working (even ICMP unreachable) and only came back to normal when the primary ASA was restored and working fine (with failover).
 
The reboot was done by shuting down the physical link between the Core switch and ASA inside individually.
 
I am not sure what could be the issue that the servers in the DMZ wen unreachable.

Cisco Firewall :: ASA5580-20 High Cpu Utilization In System Context

Nov 7, 2011

We have an active-active pair of cisco ASA5580-20 with software version 8.4(1)9. There are 8 contexts on it (including admin and system). 1 context is active on Primary node and other 7 are active on Secondary node. User traffic is going through this 1 context (2 interfaces - inside to users, outside to internet) and there are peaks to 1.16M concurrent connections, max bandwidth is 1.25Gbps. CPU usage for this context in peak hours is 63%, but we noticed that when we run "show cpu usage context all" from system it shows that system context is using 25% of CPU and "Total CPU utilization" (form output of show cpu detailed - on system context) is 88% which is bad. In non peak hours - user context use 33.6% CPU, system use 14.5%, total CPU usage is 50.5% So, is it normal this cpu utilization on system context (system on Primary node)?

Cisco Firewall :: 5520 High Memory Usage And Error Creating Access Rules

Feb 13, 2013

I'm having a problem with the memory and also trying to create some rules on the CISCO ASA. The version that I got installed was the 8.2.5.33 on a CISCO 5520 with 512 RAM, the memory usage is on 99% used, 1% free and because of that when I'm trying to create a new rule the firewall brings me the next error..So what I did was a downgrade to the version 8.2 (4) 4 and the memory went down a little (82% used, 18% free) but I still got the error when I'm creating an access rule on the device. One thing and I'm not sure if this could affect on the performance are the number of access list and the object groups that are created.
 
I already open a case with CISCO TAC and they are checking if the problem is with the memory capacity or maybe a memory leak.Also the doubt that I got is with the memory that I got now available should I can create access rules or 82 is still to hig to create a rule or and object group?
