Well I have now added kdb and invariants/witness support to the kernel so I should be able to get some backtrace the next time it happens. Currently, the system just locks and no error is displayed on the console or /var/log/messages; sorry I cannot be of immediate help there. Regarding the rpc issue, I just ran across mention of those in sshfs/nfs threads appearing here and in particular to a link referenced within one of them (http://docs.freebsd.org/cgi/getmsg.cgi?fetch=1362611+0 +archive/2006/freebsd-stable/20060702.freebsd-stable ) - it is more than likely not at all related but I am grasping at straws here trying to solve this. FWIW, I do see the following appearing in the /var/log/messages: ufs_rename: fvp == tvp (can't happen) about once or twice a day, but cannot correlate those to lockup. Now that I have enabled the options mentioned above in the kernel, I am seeing some LOR issues: kernel: lock order reversal: kernel: 1st 0xffffff00c3bab200 kqueue (kqueue) @ /usr/src/sys/kern/kern_event.c:1547 kernel: 2nd 0xffffff0005bb6078 struct mount mtx (struct mount mtx) @ /usr/src/sys/ufs/ufs/ufs_vnops.c:138 _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
