Mem leak : malloc/free + pthreads = leakage?

[Eric Anderson]

Hi all,

I have a moderately threaded userland program (all C) I am working on (using pthreads, freebsd 8.1 64bit).  It seems to leak memory (using standard malloc/free) badly.  I am using pcap to capture packets and process them. I have a handful of libs statically linked in (pcap is one, the rest don't seem to matter - I can remove them and still see the leak).  

Does anyone know of issues regarding malloc/free on multithreaded userland apps?  

Sorry, I can't post the code..

Thanks!
Eric
