The longest uptime we have achieved is 5 days conversely it has stopped daily several days in a row. When this occurs it appears there are two proceses stuck in 'tx->tx' state. In the top output shown these are snapshot-manager processes which create and destroy snapshots generally and sometime rollback filesystems to snapshots. When the lockup occurs other processes which try to access the file system can seem to end up stuck in state 'rrl->r'. The reboot command that was issued to try and reboot the server has ended up stuck in this state as can be seen. The server is not under particularly heavy load. It has remained in this state for hours. The 'deadman handler'? does not appear to restart the system. Once this has occurred there is no further disk activity. We did not experience this problem at all previously using 9.1 although we had less snapshot-manager processes before. We have built this server against 9.1 again now but it has only been going one day so far. We can try and reproduce this problem again on 9.2 if by doing so we can gather any additional information that could help resolve this problem. Please let me know what other information would be helpful. The hardware is a Dell R420 with Perc H310 raid controller in JBOD mode with the pool mirrored on two SAS disks.
