Dears,

I have issue in my wireless lan controller (WISM2) installed on 6509 E, to day i foun Memory utlization exceed from 43% to 72% without i do any thing

I wouldn't worry so much as I have a few 5508's that are just up in a lab with 50% memory utilization... just how it is. 

Thanks,

Scott

Dear,

Thanks, but my show determine any thing? to exceed the memory from 42 to 73 % and return again to 42%

Also CPU in 6509 related to that issue or not please wait your feedback.

Thanks,

[Scott Fella]

The 6500 isn't related. The WLC memory I have seen in the mid 90's with no issues.

My WiSM-2 is running 40-41%.

Personally, I'd go with Scott.  I wouldn't worry about it until the memory reaches 90%.

Dears,

I agree with you but the WISM2 memory still increased and suddenly the WISM restarted by self and i found crashed file

WISM2 Release: 7.4.100.0

Attached crashed file.

Please i wait any feedback as i see that release deffered.

Thanks

What people will tell you is to upgrade code... if a WLC crashes, you can't make any changes to prevent it from crashing.  Code upgrade is usually what people will do and TAC will suggest.  upgrade to v7.4.121.0 and make sure you upgrade the FUS.

Thanks,

Scott

Hi Scott

the FUS for my WISM2

Firmware Version................................. FPGA 1.7, Env 0.0, USB console 2.2

so please advice if i need to upgrade it when i upgrade WISM2 release from 7.4.100.0 to 7.4.121.0

Thanks,

[Scott Fella]

v7.4.121.0 is the preferred code.... v7.4.100.0 had issues especially with HA AP SSO.  So I would look into upgrading to the newer version.

Thanks,

Scott

It is recommended to... Here are the release notes so you know what is being upgraded depending on the WLC platform:
