Well, the diskcache does not work. When the cache gets full, its contents is 
corrupted. Newly created files are not seen on the client. fs flush helps...

Memory cache mostly works, but there are some problems. It seems that with 
masive parallel I/O, some writes to afs can be corrupted. If I compile the 
linux kernel in afs space with -j8, few object files can be corrupted. I can 
remove those files and the kernel builds fine at the end. Could this be 
related to disk-cache problem?

The server is 1.2.13. There are no kernel messages when the corruption apears.
I have tried that with FC3 (offical kernel) and with gentoo (gentoo kernel 
2.6.9, gcc3.4.3). 

Cheers,
Andrej
