@Stefan.

I tried "rpc/nfs debugging" as you said.

Strangely when /proc/sys/sunprc/nfs_debug and /proc/sys/sunprc/rpc_debu are set as 32767, I no longer get a crash... Perhaps the bug knows I'm looking for it!

I thought this may have some connection with me tailing the syslog with another ssh session so retested some transfers without a session checking the log - still no crash.

Setting these values back to 0 results in crashing once again.

I will try just debugging nfs and rpc seperately to see whether I can narrow the crashes down to one of them in a moment...

As for wireshark - My other Linux box has been rendered useless for the time being by me playing around with my LDAP server so I wont be able to do this test for now.

@Robbie.

I have actually tried with 8k rsize and csize which didn't help, although this was advice on the matter in some forums I came across which helped for other people - perhaps this is related.
