I'm running Samba 2.2.2 on Solaris 8 in a college environment with
approximately 200 PC workstations.  The Solaris server is a Sunfire 280R
2x750MHz, and 4GB RAM.

The end of the term is here, and the labs are near capacity for most of
the day.  As the usage has gone up, we've started to experience a lot of
problems.  I've been tracking the number of smbd processes and as they
reach 300+, it suddenly jumps to ~400, the load on the server jumps to
around 70 (from 2 or 3) and all of the processes disconnect from the

I basically have to kill off the processes by hand and restart samba to
get things straightened out.

Looking at the logs, I see quite a lot of stuff, and don't really know
what any of it means.

The "string overflow" message we have always gotten.  For some reason, the
length of the usernames is being limited to seven characters instead of
eight.  It would also be nice to stop getting that error message!

I can post the logs if anyone is interested.  Right now it's just log
level 1, but I can increase that for a short amount of time (The logs get
large as it is).

If someone can explain these errors and tell me if they could cause the
errors I am seeing, I would greatly appreciate it!
