samba - Nov 1997 - defunct smbd processes on SGI

Hello

We are running samba on SGI/SUN/HP fileservers.

We saw a problem on the SGI fileservers.
After a while a lot of defunct smbd deamons were hanging and
occupying the slots in the process table.

We saw the problem with IRIX 5.2 and samba 1.9.16p11 and
IRIX 6.2 and samba 1.9.17.p4 .

Has anybody seen this problem before? This is a serious problem, because
the smbd daemons are filling the process table, so new processen
cannot be created. Is there a solution for this problem??

I noticed exactly this problem on an SGI IRIX 6.2 system that's running
1.9.17p1 as a very light usage print server with the odd bit of file
transfer.

I shouldn't be getting anything like the following should I?

Oh yes!  We've been there -- Solaris 2.5.1 and SAMBA 1.9.15p8.
It doesn't happen very often, but when it does...  :-(  :-(
