| |
Hello all,
I have been geting some odd problems in relation to file access. Basically a process that opens / removes / or creates files randomly get stuck in the R state with no WCHAN entry with a ps auxl. I try to do a strace -p on the offending process, and strace gets stuck in the T state with WCHAN = do_signal.
The load avg goes way up, since both cpus are at 100% sys and the TIME that ps reports for those offending processes are quite high:
R p0 32:13 rm -R 02.10.99.walt.test R ? 1389:21 afpd -c 20
I also try to kill the process -9 and no luck.. Though I do see that sig as waiting in /proc for that process.
My question is: how can I tell what func the kernel is in that is causing this to happen?
I have 2 scsi controllers. 1 adaptec aha-2940UW and 1 adaptec aha-2950W. The second is connected to a 36GB hw raid box and is the filesystem these processes were using.
This is the 4th or 5th time this has happened with various processes including rpc.nfsd, afpd, rm, etc, etc.. and the only way around is to reboot and suffer through 1 or 2 fsck which take 40-60minutes each.
I am running vanilla 2.2.1 SMP on a dual PII/400 256MB Intel mainboard.
Any info is greatly appreciated!
