Fortunately it did not take too long, but unfortunately the bug is still there. :( Setup: A Quad-Opteron machine with 16 GB memory and 2.6.11-6mdksmp writes out a huge file via NFS over Gigabit-Ethernet to a fileserver. The command is: time bash -c "dd if=/dev/zero of=dump bs=1048576 count=102400; sync" Everything works well up to nearly 15GB, at that point errors show up in the syslog (see attachment) and some processes get killed. The process for file writing (rpciod) continues to draw CPU cycles but the file writing progress comes to a halt or is at least very, very slow. Strangely even on the fileserver the nfsds are still extremely active as if they would still consume 70-80MB/sec. It is somehow like the NFS protokol still works - but without data. Gwenole, did you mean the new corporate kernels address this problem or do they solve the panic at startup problem? Should I open a new bug for the NFS problem? cu Michi
