%PM-SP-4-BAD_COOKIE: bad cookie magic was detected

Unanswered Question
Apr 9th, 2009

Any ideas what causes:

%PM-SP-4-BAD_COOKIE: bad cookie magic was detected

The error message decoder states:

This message indicates that the port manager detected an invalid request. [char] is the invalid request.

But, no real answer on what to do about it.

IOS version is 12.2(33)SXH3a and didn't find any known bugs.

I have this problem too.

Hi all,

Is it possible to get more informations about this Bug? We had yesterday a client who experienced a similar issue with Prime Infrastructure on the network. Is it possible that the Campus Manager module would generate this logs in the new Prime Framework?

Thanks a lot
