Hi Sam,
my system is quiet the opposit.
P4 pc's with an 2.4.19. there are actualy 6 pc's equal 
installed/load/board but the stopps occurs mostly at random.

we have changed so far (with out success)
1. filesystem
2. shifted some load
3. changed Gfx-card ( because of DMA)
4. tried several options

checked for filepointers,memory etc.


and the error seems hard to reproduce since all tests to get the queue 
stalled at will failed so far.

i LOOKS that sometimes the workerprocess does not return/stop, no idea why.

It would be helpfull if some new algorithem for handling a large pile of 
files could be introduced (my humble attemps failed so far).

re,
walter

ps: i trying to move the a later kernel but we have some driver 
difficulties :( and i have no time to solve that, still.
