I have a Switch WS-C3750E-48PD-SF with IOS 12.2(58)SE2 which reports more than 80% in utilization of memory I don't know what is causing the high memory utilization.
View 14 RepliesI 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?

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.

I am facing high memory utilization in Cisco 2960 switch having IOS version 12.2(55)SE3.
The error we are getting is:
A "LiveHealthAlarm" event has occurred, from SwCiscoIOS device, named Switch2960. eHealth Alarm Start Time - Fri 09 Nov,2012 - 03:02:48 eHealth. Switch2960-RH-MemoryPool-Processor-Processor-1.Memory utilization high-Threshold set at 70%SPECTRUM ALARM ID|22233284 I have attached the logs also.
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.
I upgraded the newest IOS 15.0(1)SE for our SW C2960-24-TT-L, the process was succeseful. However, we found SW memory utilization raised to 82% this morning in normal situation. (Momery: Total 21341260, Used17471692) Did you guys meet the same problem after upgrading to 15.0(1)SE? I also would like to know what the normal memory utilization is? and what is the impact of memory utilization highly?

In addition of this, the IOS installed on VSS 6500 is s72033-ipservicesk9_wan-vz.122-33.SXI6.bin for checking if there are some bugs affecting the behaviour of the Switch for this case.

I've been looking at reported problems with our Vdeio Conferencing kit attched to a stack of 3750's (which I think is down to QoS) but this got me looking at the logs. We get a lot of high CPU utilization warnings mainly for SNMP (315), Hulc running con (95), Virtual exec (289). I understand the last two are normal, and the SNMP one is probably Cisco Works polling as it happens every 4 hours.
However I've got an odd one: Apr 25 07:34:58: %SYS-1-CPURISINGTHRESHOLD: Threshold: Total CPU Utilization(Total/Intr): 93%/0%, Top 3 processes(Pid/Util): 296/85%, 144/0%, 154/0%

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)
We 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?
In Cisco 3750 facing high CPU utilization for specific period. During this period traffic response times across the switch degrades. Steps to identify interface potentially generating traffic. I have attached 'sh proc cpu history' , ' sh ip traffic', 'sh proc cpu sorted' during troubled period .

View 4 Replies View RelatedWe 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
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?
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)

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 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.
View 8 Replies View RelatedWe 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.
