[AGENT++] memory leak

[Meena Nallasivan]

Hi,

We ran the SnmpWalk for overnight as a part of our performance test

After 12 hours the system crashed, from the traces attached below it
looks like there is a memory leak.


Can you clarify the following points

1. Are we using the memory from the system directly for "new" operator,
or if there is any Memory pool maintained?

2. in mib.cpp file, please find the code snippet below

#ifdef AGENTPP_USE_THREAD_POOL
        MibTask* mt = new MibTask(call);
        threadPool->execute(mt);

I don't see "mt" getting released anywhere? Am I missing something?

Regards,
Meena
