System: NetBSD chicken-ac.apt.columbia.edu 2.0.2 NetBSD 2.0.2 (GENERIC) #0: Tue Mar 22 16:19:08 UTC 2005 email@example.com:/home/builds/ab/netbsd-2-0-2-RELEASE/macppc/200503220140Z-obj/home/builds/ab/netbsd-2-0-2-RELEASE/src/sys/arch/macppc/compile/GENERIC macppc
I installed 3.0_STABLE on a PowerPC Mac mini a few weeks ago. I
put the machine through its paces by rebuilding itself from src
and 250-odd packages in a pkg_comp. So far, so good. But when I
brought it into production, I started getting odd signal 11s from
at least MySQL and Dovecot. (MySQL would also eat a table or two
every day; nothing REPAIR TABLE couldn't fix, but yikes.)
After trying 3.0.1 and then a 3.99.23 kernel without improvement,
I rolled back to 2.0.2 on a tip from another mini owner. With the
exception of one failed pthread assertion, from which MySQL recovered
by restarting itself with no visible damage, the mini has been rock
solid for the last week-plus.
I'm not in a position to experiment further on this machine, as
I'm relying on it, but wanted to make sure I recorded this problem
Install 2.0.2 on Mac mini; leave it running for a while until
convinced it works well. Install 3.0.1 on same machine; notice
fairly quickly that daemons are dying strangely. I have a trace
from a dead Dovecot, though it doesn't look too useful to me:
