We actually had some other problem with our software running on that machine, related somehow to the network, but since the whole thing was in the alpha stage, we blamed ourselves for that and scheduled it for further investigations ... :-/ . By the way, do you know any "easy" way to spot the problem? Maybe a setup for debugging the module or a simple user application that can reproduce the problem - a test case ?
Bottom line, next time when it hangs I think I'll try :
1. change the eepro100 module.
2. completely disable the quota daemon.
Thanks everybody.

Are you "sure" it's not the network itself?
I've had problems with Redhat 8.0 and the Intel EPro 100 driver. Changing it from "eepro100" to "e100" clears up the problem.
Just a shot in the dark.

Hi everybody !
After we installed a fresh RedHat 8.0 on a 2 processor machine the NFS daemon hangs from time to time - really badly, since I cannot kill it with -9. The problem occurs every couples of days.
I cannot even reboot, because the reboot process will hang trying to kill the NFS daemon. The problem is that after I try to kill nfsd, the exported partitions are not accessible, even locally - every access just hangs. Also, umount will report that the partition is busy. Just to make it clear:
- the nfsd hangs (I cannot access the exported partition from any client)
- the partition is still accessible locally
- try (unsuccessfully) to kill nfsd
- the partition is not accessible anymore
There is no processor activity when it hangs – both processors are idle. Also looks like there is no disk activity.
Now, the partitions are some big (1TB) RAID disks. The RAID system is a separate box, accessible through a SCSI interface. So the computer will see just one big disk. Actually there are two of them, on different LUNs: 0 and 1. It worked fine before the upgrade, but because of a old kernel only LUN0 was accessible.
Here are the details :
processor: two Pentium III (Coppermine) at 800MHz, 256KB cache
memory: 2GB
kernel version: 2.4.18-19.8.0smp (upgraded with up2date)
I think there is no need to say that any suggestions to solve this problem are extremely welcome :-)
Cheers,
iulian
