Hi there,

Anytime you see 'traceback' in your logs you should be considered. A process has crashed and is dumping i a stack trace to the log you could debug it... in reality you will not be able to without the help of TAC and instead these memory will reality unclaimed and lead to a memory leak.

There are several published bugs relating to 'hpm main process' . What platform and software version are you running?

cheers,

Seb.

...personally I would upgrade the switch to the recommended release 15.2(4)E7:

Yes, it is the recommended release for your platform. The recommended release is typically chosen based on the number of revisions it has received. Fro this you ca infer it should have the most number of resolved caveats and least number of bugs.

cheers,
