Cisco Firewall :: High Cpu Utilization On Pix 515E?

Aug 9, 2012

I am facing high CPU util on my pix 515 E which is in failover mode.During peak hours the util is see rising to 60% where as in off peak hours it is normally12%.
 
During normal operation the average utilisation was observed to be 30% but suddenly from 2/3 days it is constantly 60% doule the value as earlier. Have gone through the logs and traffic but not able to tarce anything particular
 
below is the o/p of some command taken for analysis
 
IOS version 8.0(4) 
sh cpu usage
CPU utilization for 5 seconds = 51%; 1 minute: 61%; 5 minutes: 58%
sh cpu usage

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 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 :: High CPU Utilization On ASA 5540

May 11, 2008

I have a remote site customer with a Cisco ASA 5540 running SSLVPN (Anyconnect)(8.03). It currently only serves about 450 SSLVPN clients. Since last friday, they've seen the CPU utilization go up to high 90% while only serving 400+ remote users. I saw some high cpu utilization bugs, but none looked to be relevant. How I can find the root cause of the CPU high utilization?

Cisco Firewall :: PIX525 Sudden High CPU Utilization?

Feb 22, 2013

Would like to ask for everyones assistance with regards to the problems we are encountering on our PIX525 firewall. Our encountered problem is as follow."PIX 525 experience sudden high CPU utilization every time a Vulnerability System Scan (third part app) is conducted. Based on the previous experiences, the high CPU utilization where experience when a host on a particular VLAN (214) is being scanned. Whenever we removed the said VLAN (214) in the network the CPU utilization of PIX 525 comes back to normal and all connectivity were resumed."The problem just recently appeared, we are conducting vulnerability system scan before and it goes successfully.

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 :: 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 WAN :: 2811 High Cpu Utilization

Apr 29, 2013

I have a 2811 that is really hitting the CPU hard.  Nothing shows on CPU processes.  It has an IPsec VPN tunnel back to HQ which also has a 2811 that terminates the VPN.  The HQ has 2-3 IPsec tunnels to other remote sites.  The CPU at the HQ avg 50% utilization during business hrs, peaks at about 80%.  The remote one is very high 95% peaks, avg 80%-95% during business hours with bandwidth utilization of only 10-20Mbps.  I read somewhere that its possible that fragmentation could be causing this.  My question is, if I set the MTU to 1450 on the remote, I am guessing I will need to do all the other routers as well, the HQ and other remote sites?  Siince they use the same outside interface to my HQ, is that correct?

Cisco :: 7613 Having Frequent High CPU Utilization?

Apr 25, 2012

I have Cisco 7613 on my edge(MPLS Backbone). CPU utilization is shooting to 100% at frequent intervals. When I tell vendors managing device they tell that it is happening due to one of my server(connected on Fast ethernet port of 100Mbps) generating heavy traffic. My questions are:

1. Can a router of 720Gbps capability be choked due to traffic generated by 100Mbps link?

2. Interrupt CPU process utilization is well below 10% at the said time. BGP router process consumes most of the CPU. Does this means that server in question is generating too many routing updates?

3. Is there any way that I can limit routing updates on a particular link?

4. how to check which link is causing more CPU utilization.

- voice calls
- ospf
 
The ospf  is not the cause of the high cpu , because the high cpu utilization appears before I put the ospf proccess on the router.
