:(
The upgrade to kernel 2.4.20-19 did not help, today again, I had to 
restart the NFS service due to the "getfh failed: Operation not 
permitted." error.
I've compared the logs (Aug 4th and today). What is interesting is that 
the VFS quota error appeared again today, too. The quota bug occured 
first at 6am and continued happening about once an hour till  11:45am. 
45' later, the first getfh error appears in the logs. Short after that, 
I've restarted the NFS service.

I'd love to help debugging this problem. I'd appreciate some pointers 
where to start, though. How can I provide debugging infos while still 
keeping the machine in production?

What I may try is running vanilla kernel 2.4.22 (once it's out), too, I 
saw that there are improvements for machines with heavy I/O load.

TIA

Regards,

    Marc
