Mysterious hangs with Fedora
Date: Wed, 31 Mar 2004 05:29:29 +0100 To: firstname.lastname@example.org
I'm experiencing a very weird situation with FC1.
I have this machine that was upgraded from RH9 to FC1, using yum. Everything
worked fine, no problem there.
When running RH9, this machine was rock solid and only rebooted for kernel
updates. But with FC1, the problems began.
The machine completely hangs, with no apparent reason whatsoever, at no specific
time. I tried lots of kernels.. my usual custom vanilla+grsec and RH9's 2.4.18
and Fedora's latest NPTL kernel. That appears to make no difference. However,
there was this occasion when i noticed the machine hanged two days in a row at
exactly the same time, when running cron.daily (updatedb?!). But i never got to
reproduce that sistematically. Yesterday i stressed tested it with a full
backup (tar+gzip) and kernel compilations at the same time. Went great. Then i
went to bed, to find in the morning it crashed around 30mins after that test,
when idle.. I can have a week uptime, or 3 hangs in a day, depends on it's
mood. The machine does pretty much the same thing all the time: mail and web,
nothing fancy and nothing else.
The hardware is a Tyan 1U rackmount, 2.4 P4, 1GB DDR, two 120GB IDE disks in
RAID1 (Promise FastTrack controller onboard). Hardware worked before for
months, no problem. All fans ok, so overheating does not seem like a
possibility. The only changed variable is the upgrade from RH9 to FC1. However,
same behaviour with very different kernels, that also confuses me. Some quirk
with glibc maybe?
Anyone here experiencing something similar? Any thoughts? Before i switch back
to RH9 and see if it helps..
Thanks in advance
