I found something in the vmcore.0

panic: Journal overflow (joffset=499758276096 active=498475869184
inactive=499755984896)
cpuid = 0
Uptime: 16h7m11s

I tried kgdb on on the vmcore but it didn't work, I had -p2 installed,
but compiled p6 so it might of overwrittin things in /usr/obj

The journal was set to 2GB on the 400GB USB attached disk. (/dev/da0)

I just formatted the disk without gjournal and see how that goes. I
guess i can't use gjournal over USB? I have gjournal running on
another server (gmirror + gjournal) and i thrash it pretty hard
without any problems.

Has any new patches for gjournal been included in 7.1?

Thanks for the help
