Did so, the mount locked up and still is, ready for some more experimentation. I don't see any difference however. Did a echo 0 >/proc/sys/sunrpc/rpc_debug afterwards (see below). A recipe which seems to trigger the issue (at least occasionally) is cd /mount-point ssh server echo 3 \>/proc/sys/vm/drop_caches echo 3 >/proc/sys/vm/drop_caches for i in `seq 100` do du >/dev/null 2>&1 & done I'll try it on a pristine kernel to rule out some kernel patches (unlikely to be the cause or trigger but just to be sure). -pid- flgs status -client- --rqstp- -timeout ---ops-- 29785 0080
