Hi,
After 370 days of uptime, I suddenly got an "ffs_valloc: dup alloc"
panic under our production server, for the swap partition.

After a reboot in single-user mode, fsck found 200+ errors (a lot of
soft updates inconsistencies, plus others), but corrected them
apparently well. At the next reboot, except a few things, everything
works fine, but this is quite frightening.
The server has an INTEL SRCU42L card, with RAID 5, firmware
2.34.05-R043. (iir driver)
What would you change first in order to correct that problem? OS patch
release? OS version? Raid firmware?
The odd thing here is that swap ist not used at all on this server,
built with 4 GB and where no more than 2 GB is being used.
Thanks!
Regards,
