Hello All,

There is something strange on my mail server running 6.2-STABLE:

# ls -l
total 1239702
- -rw-------  1 vscan  vscan  4398199488512 Jun 20 15:18 auto-whitelist
- -rw-------  1 vscan  vscan             22 Jun 20 15:18 bayes.lock
- -rw-------  1 vscan  vscan         102168 Jun 20 15:18 bayes_journal
- -rw-------  1 vscan  vscan  1099639861248 Jun 20 15:18 bayes_seen
- -rw-------  1 vscan  vscan       21057536 Jun 20 15:18 bayes_toks

but:
# df -h
Filesystem     Size    Used   Avail Capacity  Mounted on
/dev/ar0s1a     19G    3.9G     14G    22%    /
...

# du
1239758 .

# mount
/dev/ar0s1a on / (ufs, local)
...

When I try to delete some entries from auto-whitelist:
Out of memory during request for 52 bytes, total sbrk() is 536223744 bytes!
Out of memory during request for 56 bytes, total sbrk() is 536223744 bytes!

Any ideas?
