MALLOCFAIL with Pool Manager

[Rojer-bkk]

Hi,

I got various error about memory allocation failure. I user sup720 with IOS 12.2(18)SXD7b. Should it be software issuue?

-Process= "Pool Manager", ipl= 0, pid= 6

Has this sup720 been running for a while and then this happened? Or did this error happen shortly after the sup720 booted up?

I see that there are traceback messages in your output. Traceback error messages are almost always an indication that there is a software problem rather than a hardware problem.

If you open a TAC Case, the first thing they'll ask you is post the output to the "sh module".  This'll help determine WHY you are still using a very ancient IOS version, a significant part of the TAC were still in their diapers.

Hi Rojer

The error logs are generic indicating MALLOC failure, as its a old code there could be any bug hitting and could be causing the memory leak. so recommend you to upgrade to the latest code.

# show mem debug leak

#sh memory debug leaks chunks

- These commands will help you identify in case any memory leak is there.

Thanks & Regards

Sandeep.

Hi all,

Thanks for sharing information and command. The command look like are not available for 12.2(18)SXD release. I noticed the error identify about DFC10 so i will try to reseat card first. I understand the IOS is quiet old (since 2006), but  need to upgrade flash memory (current 64MB).
