as opposed to what? OpenBSD? Linux? Windows? why do you think your problem is specific to FreeBSD (as evidenced by your post to a FreeBSD-specific list) or is related to threaded 
programs?

hell yeah. it goes like this: you malloc() then forget to free() - boom, you have a memory leak.

you're welcome.


sarcasm aside, those questions still remain: why do you think os/libraries are the problem and not your code?
you can't post all of it, ok, and we don't want all of it either. can you isolate a specific example of where valid usage of a library causes a leak?
