I have mail hub, running zmailer at linux RH 4.2, 2.0.35 kernel.
Hardware: 2xPPro 200Mhz,Moterboard ASUS, 64Mb RAM, SCSI DPT PM2144UW with 32 mb
onboard, 2 4GB Seagate, configured as RAID 1 using DPT controller.
During last few month I upgraded kernel from 2.0.31 -> 2.0.34 ->2.0.35 with the
same configuration.
At 2.0.34 I started to get crashes with following diagnostics approximately once
every 2 month.
Aiee:Scheduling in interrupt xxxxxxx
[about 20 the same messages]
Aiee:Scheduling in interrupt xxxxxxx
IRQ DEADLOCK DETECTED BY CPU0
No any other messages ws found before this diagnostics and no messages was
written into system log.
Tracing address have shown that error address always inside __wait_on_buffer
function.
Approximately at the time of switching to 2.0.35 I changed configuration of
zmailer and made a mistake there. Because of mistake I got a lot of mail looping
between 2 machines, so load and disk activity significantly increased ( about
10-15 mails per second ). Under this load I started to get this message
approximately every 2 hours. Mailer configuration error was found after that and
everything went back to peaceful 1 crash per month state ( at least I hope so
;))
I run memtest86 on this hardware for 3 days with 0 errors.
Any suggestions ?
Alex
