Hmm... I'm still not convinced... I have used MySQL from .22 up to .32 and I have
experienced periodic (about once a month, strangely) signal 11s on all of them,
both on solaris and freebsd. I finally resorted to restarting mysql in the dead of
night, and since then (.32, freebsd-3.4-stable), it's been just fine... The crashes
always happened under low load in the wee hours.
Not like I tried a debugger or anything...
