>Description:
After doing a source upgrade of FreeBSD 7.0-RELEASE to 7.1-RELEASE I am consistently seeing a panic, approximately 25-35 minutes after each boot. At the time the system is effectively idle (it's a MySQL server, but mysqld has been disabled at startup while I diagnose the problem). Two notable exceptions: gmirror is rebuilding two mirrors, and fsck_ufs is checking the file systems. Based on some quick research I suspect it's the latter that is causing the panic. If so I'm stuck in a vicious cycle since the file system is going to be checked after every crash...
This is what the panic output shows:
------
dev = stripe/raid10, block = 1, fs = /db
panic: ffs_blkfree: freeing free block
cpuid = 1
GEOM_MIRROR: Device db2: rebuilding provider ad16 stopped.
GEOM_MIRROR: Device db1: rebuilding provider ad12 stopped.
Uptime: 31m16s
Physical memory: 8183 MB
Dumping: 656 MB:
<system freezes at this point>
------
Note 1: /db is a stripe (name: "raid10") of two mirrors (names: "db1", "db2"), approx 1.5TB of usable size.
