That's probably a good idea. Where would I find out what other projects use it?

I just mean that when I debug and catch the segv, it's dies because some pointers now have corrupted values. (usually because something is overwriting some memory some where)

I'm currently re-writing some code to make it use select() instead of epoll_wait() and see if everything is suddently fixed. If so, then I will suspect that epoll has a problem. But it's still not ruled out being my fault since it could be a timing issue that makes the crash show up.



Just out of curiosity, have you had the opportunity to read some other
code which uses epoll ? Maybe reading others code could enlighten you
on potential bugs in your code, potential races, etc...
