We use mongrel to host a small network-based mediaplayer. Basicly http-requests with the media as body, that gets played with mplayer.
Lately we've been having some random crashes, which really shouldn't happen as every request is wrapped in a begin-rescue clause. After starting our media-player in a screen instead of a daemon we noticed the cause was mongrel seg-faulting. Now I can't reproduce it, but it happens from time to time (every couple of days).
