High Memory Utilization SW 3750

[Adrian Caba Gutierrez]

Hello, 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.

I attached a file with some outputs of commands.

Thanks.

Sorry I forget attach the file.

Don't need to look at the file.  I saw your IOS level and it's enough information for me.

For 3750, there'a memory leak affecting the ENTIRE 12.2(58)SE train (SE, SE1 and SE2).  Avoid 15.0(1)SE, SE1 and SE2.  You could try 15.0(1)SE3.  You can also try 15.0(2)SE.

The "most safest" IOS for the 3750 (Layer 2 or Layer 3) is 12.2(55)SE5 or SE6.

Hi Leo,

Don't you think Cisco should remove all the 12.2(58) and 15.0(1) Catalyst IOSes from the download section of their web? It makes much more harm to leave it there.

Best regards,

Peter

No offense, Peter.  Please don't get me started.  I asked the same question.  You do not want to know the response I got from TAC.

I have the service of Smart Call Home so  I need the 12.2(58) or higher, there is some related to this service to cause this problem because I have other switch 3560v2 with the same problem and other switches 3750 that don't have this problem. Also I had other problem of high cpu, I removed the configuration of Smart Call Home and the problem ended.

Thanks for the help.

The first time I've seen the High-CPU bug on the 12.2(58)SE and SE1 was on a 2960-48 PoE.  The switch DID NOT HAVE any configuration on it.

You have no idea how fast I had downgrade my fleet of switches away from this IOS version.

The configuration of SmartCall does not trigger the High CPU.  It's the HULC.

Adrian,

Not all high memory issues are due to software bugs. If possible, please collect the output of 'show version' 'show memory alloc totals' and 'show process mem 381'. From the configs, I see mutiple instances of the process 'EEM Callback Thr'.

Please post config related to EEM.Maybe it could be misconfiguration with EEM.

Also check how long the switch been up and the trend in memory utilization.

Thanks

These IOS versión have many problems but I need this versión for the support of SmartCall Home. Subramaniya I attach the outputs that you say, I don't know so much about the configurations of EEM I think that have not this configuration.

The high memory utilization began five days ago I didn't make no one configuration on the switch.

Thanks.

Smart Call Home was supported on 12.2(58)SE.  Since this entire train is "wierd", try 15.0(2)SE. 

[Adrian Caba Gutierrez]

Thansk for the help I will make the upgrade and will post the results.

Hello Adrian,

we use the following version and works fine sine a few months,15.0(1)SE3.

Regards.

[Adrian Caba Gutierrez]

Somebody tried the version 15.0(2)SE since the 15.0(1)SE3 is not longer available in the web page of Cisco.

Thanks.

See you the attached files.

Regards.

[Adrian Caba Gutierrez]

Hi Iker, Sorry you are right the version is still published.

Thanks.
