Default 2.6.18-194.26.1.el5 NFS4 race conditions?

Are there any known race conditions with 2.6.18-194.26.1.el5 x86_64 and
NFS4?

Today a user managed to shut down two identical Intel servers by copying
a simple text file via NFS4.

Reverting back to 17.1 made the error disappear.

On other non-identical hardware the error was not reproducible (so it
must be a combination of hardware and this special kernel revision).

Anybody interested in a kernel dump? It's only 16GB. I could install
kernel-debuginfo and try to get something out of the dump..
