Hey guys, I use MEncoder for transcoding purposes, and lately with x264 multi-threading enabled, the system sends SIGPROF to it and it crashes. I hacked the source up a little bit and put a signal handler in for SIGPROF that keeps the program from crashing, but I'd like to figure out a little more about the problem so I can figure out what's really going on. Running strace occurred to me, but the output would be huge considering it's mencoder and it usually doesn't get a SIGPROF until the middle of encoding.

I think that I could probably do good with strace -e signal=SIGPROF, but I need some general advice. I just know a little bit of C and my away around Linux a good bit, not really a developer--certainly not enough of one to think about submitting a bug report yet. I think it's got more to do with my system than MEncoder anyway.

Anyway, any advice would be appreciated. I'm concerned about why it's getting a SIGPROF anyway and what other applications might end up being affected.
