This has never happened before, and I don't know what to look for in this debug info. The plugins I have are:?
crashdetect?mysqlR41 timerfix regex?sscanf YSF streamer


Server is 0.3.7.
All the plugins are up to date with their latest versions. I've started using?YSF since yesterday?(version?is the newest R20-RC4), so maybe that can be the problem. Is it possible to know for sure what has caused this crash?
