Cisco Switching/Routing :: 2960 High Memory Utilization
May 2, 2013I 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.

Cisco Infrastructure :: 2960 - High I / O Memory Utilization
Oct 26, 2011We 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.

i want to understand why this 2 proceses (DHCPD & ARP input) taking more memory?High CPU: We also facing intermediate high CPU utilization (above 95%). When CPU is high there were 2 processes consuming more CPU are 'Spanning Tree' (about 20%) & ARP Input (about 66%). we also checked the ARP entries, there were 1500 ARP entries & 2 incomplete ARP (out of 6000 ARP supported)
Cisco Switching/Routing :: 3750 Stack - High Memory Utilization?
Jan 21, 2012I have a new cisco 3750 stack comprised of 8 members (6 x 3750G-48PS and 2 x 3750V2-48PS) running 'c3750-ipservicesk9-mz.122-58.SE2.bin'. I am seeing high memory utilisation, it seems to sit fairly stable and I do not see an increase but this has only been running a few days. No errors or performance issues. Should this be a cause for concern?

Jun 11, 2013We 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 Switching/Routing :: Can TCAM Memory Cause High CPU On 3750 Stack
Sep 12, 2012We have a 3750 stack with a mix of 3750G and 3750X switches. The current active template on the switch is desktop default and we are running EIGRP on the switch with large routing table so we get the TCAM error that a specific prefix cannot be programmed in TCAM memory so it will be software forwarded.%PLATFORM_UCAST-4-PREFIX: One or more, more specific prefixes could not be programmed into TCAM and are being covered by a less specific prefix, and the packets may be software forwarded
This error is quite frequent on a daily basis. My question is that will this error create a high CPU situation and affect traffic processing on the stack causing ESX Hosts to become unresponsive?

Cisco Switching/Routing :: Memory Leak On Catalyst 2960 And 2960S - Similar To Bug CSCts52797
May 6, 2013after upgrading about 35 Catalyst 2960 and Catalyst 2960S to IOS 15.0(2)SE2, we experience a memory leak on several switches. After some days / weeks the switches are not accessible via Console/Telnet/SSH/Web any more. Only SNMP seems to work properly.Attached users do not experience any decrease in service.
Trying to connect to the console, we get following error message:
"% Low on memory; try again later"
The only (temporary) solution is to reboot the switch. The behavior is similar to Bug CSCts52797.With regards to the Bug notes this bug should only affect Catalyst 2960 with 64MB of RAM and should already be solved with IOS 15.0(2)SE2.
We experience the erroneous behavior with
-WS-C2960-48TC-S running IOS 15.0(2)SE2
-WS-C2960S-48LPS-L running IOS 15.0(2)SE2
Cisco Switching/Routing :: 2960 High Output Drops
Aug 2, 2010I have quite a few 2960's in a manufacturing environment that are experiencing a large number of Total Output Drops. The gigabit uplinks arn't even close to fully subscribed and if I'm lucky they run at a peak of 4 - 5 Mb on a 1Gb uplink. Something really funky is going on. The individual switchports seem to have the total output drops and the uplinks at 1Gb do not have any output drops and never peak above 20Mb over a 3 month span on a 1Gb link.

Jul 29, 2012We 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.

Cisco Firewall :: Very High Memory Utilization In PIX 515e?
Feb 15, 2012We 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 :: High Memory Utilization After Few Days - Ciscoworks LMS 4.0.1
Sep 18, 2011I 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.

Feb 13, 2013I'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?
