[c-nsp] Memory leak

[Javier Castillo Alcibar]

This process, "TCP Protocols" is increasing, over the time, its
Allocated memory, but nerver frees memory.......How can I know which
process is deallocating those blocks?

I did some searchs in the bug toolkit, and I found some bugs related
with memory leaks, but none of them seem to be related with my
problem.....

BTW, the "Memory Leak Detector" feature, can help me in this case?

Javier.

Just because a process allocates a block doesn't mean it is the only one
that can free the same block.

Monitor 'sh proc mem' over time and if the free amount keeps decreasing
them compare 'sh process memory' to find the one that is holding more
and more memory.

Then monitor: sh proc mem <PID> for that process and open a TAC case for
it so they can decode the functions for those PC's.
