I recently have been seeing the console and messages flooded with the following:

Oct 27 00:00:01 deimos /kernel.old: negative sbsize for uid = 0
Oct 27 00:00:34 deimos last message repeated 131 times

I haven't altered the Kernel since April.

This appears to have mostly started happening when I attempted to
mount_smbfs a share from a windows system.  The performance was
overwhelmingly slow and I thought whatever was causing it may have
been fixed in a later version.  I then upgraded Samba to 3.0.7 from
ports.  Was previously using 2.2.12, also from ports.

Even after not attempting to remount that windows share, I'm still
receiving tons of the sbsize for uid = 0 messages.

I appreciate any help someone can give :)
