sync hanging

[Corin Hartland-Swann]

Hi there,

I'm using kernel 2.4.8-ac2 on a Dual PIII-1000 with 4096M RAM, and a
reiserfs filesystem on a RAID-1 mirror of two 76GB UDMA disks, and I'm
experiencing a strange problem after the machine has been running for a
while.

Every now and again, running sync(1) (i.e. the program) seems to hang and
end up in state D (uninterruptible sleep). There is no way to kill it
(even with SIGKILL but I assume that this is typical for state D
processes.

Does anyone have any idea what may be causing this? I have searched the
archives and couldn't find anything similar.

Thanks,

Corin
