Hi all!
I have recently installed samba-3.0.2a-1 on my RedHat 9.0, Kernel
2.4.20-8 box. The box has a 300GB RAID5 array, 4GB of memory, and dual
2.4Ghz P4 processors with hyper threading enabled.
When I copy a massive amount of files (~50GB) to the Samba server
from a Windows 2K client, somewhere during that process (seemingly around 2
hours into the copy each time), my Linux box COMPLETELY locks up. I must
hard reset it. This behavior is consistently reproducible. When I do not
copy files, the box never locks up. I have hard limits set in
/etc/security/limits.conf so if Samba is consuming all resources, I don't
know how. I set a process to capture the output of "ps" every 5 seconds and
the last output it gave before the box locked up was this (relevant portions
only):
root 4 0.0 0.0 0 0 ? SWN Jun02 0:00
[ksoftirqd_CPU0]
root 9 0.0 0.0 0 0 ? SW Jun02 0:00 [bdflush]
root 5 0.1 0.0 0 0 ? RW Jun02 0:19 [kswapd]
xfs 4913 0.0 0.0 4524 3080 ? S Jun02 0:00 [xfs]
root 5636 0.0 0.0 9652 2444 ? S 00:18 0:00
/usr/sbin/smbd -D
smbguest 5693 6.4 0.1 13948 7132 ? S 00:20 9:15 \_ [smbd]
root 5638 0.0 0.0 7796 1980 ? S 00:18 0:00
/usr/sbin/nmbd -D
The last "uptime" output before the crash was:
02:43:59 up 2:50, 2 users, load average: 0.60, 0.47, 0.46
My limits.conf file:
* hard core 0
* hard rss 100000
* hard nproc 30
Any thoughts on the matter? Thanks for any help!
Respectfully,
Matthew Connor
