next in thread | raw e-mail | index | archive | help
Greetings,
I have a very strange problem. I am administering a number of FreeBSD
machines (64bit) with:
9.3-STABLE
and after the upgrade to 9.3 for the past months until now I have noticed
that every day at approximately
the same time the machines reboot by watchdog timeout. I believe the problem
lies on an entry on the crontab which is difficult to debug because the
crontab has too many entries [280 lines].
All the previous versions of freebsd worked fine (even 9.2) and had uptime
for many months.
After going to 9.3 the problem arose.
I have made debugging symbols for all the kernels and I have some logs of
it, in case you can help me debug this strange problem.
The watchdog fires almost every day in the morning (not exactly at the same
minute), as the log files bellow show. Some days they skip the reboot.
NOTE: This happens in every FreeBSD server that I have updated to 9-3 even
with different hardware.
If I kill the crontab no reboot will happen (at least for 3 days that I
tried it).
All the servers bear similar crontab.
The watchdog flags:
watchdogd_flags="-s 30 -t 60 -e /bin/ps"
As you know after 3:00 a lot of house cleaning jobs take place and cpu
raises load, but I believe that
the kernel should not reboot in such situations.
I am reluctant to try:
-disable watchdog, because these servers are required to operate and if they
go down and do not reboot, some users will be upset
-comment one-by-one every process in the crontab, because this will required
a couple of months debugging.
==>Any clever way how to spot the bug?
1st Machine [This is a real physical machine]:
{NOTE: For many days I had disabled crontab and thus the reboot are less in
this month.}
