[OpenAFS] Connection timed out?

We are evaluating OpenAFS for use with 50 clients. One of the tests is a
kernel build on 50 clients at the same time.

During this test we encounter 'Permission denied' errors, which seem to
coincide with 'kernel: afs: failed to store file (110)' entries in
/var/log/messages. 110=Connection timed out. The fileserver is busy but
responsive, about 25 builds (out of 50) complete normally.

We are running 1.4.8 client & server, kernel > 2.6.18 64-bits. Currently
all server processes run on the same server. Fileserver settings:
/usr/afs/bin/fileserver -p 128 -b 512 -l 3072 -s 3072 -vc 3072 -cb 65536
-busyat 1536 -rxpck 1024 -nojumbo

What are we doing wrong (except for the way we test;-))?
