This is a i386 current SMP box as of Apr 14 or 15. Got
a panic with geom journal.
panic: Journal overflow (joffset=3246704015360 active=3246705852416 inactive=324

Sorry, that I don't have core dump available. Will set up next time.
After the panic, the system hangs at single user prompt:

Unknown error; help!
AEnter full pathname of shell or RETURN for /bin/sh:

I need to issue 'fsck_ffs -p' myself... any idea about why this happens?
The geom journal setup:
Geom name: gjournal 68372861

Role: Data,Journal
The gconcat consists two scsi disk (actually, it's raid) da0 and da1.
Oh no, it panics with journal overflow again while writing this message :(
The data.journal is shared by nfs, and there are two boxes that are
doing a tar writing operation on this partition.
