Every 4-8 days my news server (~10 full incoming feeds, ~50
outgoing feeds) crash:
panic: blkfree: freeing free block
or
panic: blkfree: freeing free frag
I have a P6-200 rinning on a ASUS P65UP5+C-P6ND (BIOS rev. 2.05),
with 512M ECC of RAM (with David Greenman patch).
news spool is 6x4G Barracuda (ST15150W) CCD across two 2940UW.

This server is also ftp server (ftp2.ru.freebsd.org).
ftp disks are nfs exported.
Last crash (Dec 5, 13:15):
dev=0x1502, block=20372, fs=/var/spool/news
panic: blkfree: freeing free frag
syncing disk
(unfortunately at this point the system is freeze and I have
make the hardware reset, so I don't have crash dump).
