dup alloc, please advice

[Pavel Merdine]

Hello,

/kernel: mode = 040700, inum = 12, fs = /somemount
/kernel: panic: ffs_valloc: dup alloc
/kernel:
/kernel: syncing disks... 49 22 8 7 7 7 7 7 7 7 7 7 7 7

It happened just in 10 minutes after fsck.
There are lots of writes to that disk by many nfs clients at the same
times.

What should I do in such situations?

FreeBSD 4.10-STABLE #0: Mon Jul 26 05:46:38 EDT 2004

By the way, sometimes I also get
/kernel: ufs_rename: fvp == tvp (can't happen)
in logs.
