Hi!
I'm running 3.0.21b on OpenBSD 3.8-stable (i386) with raidframe. Without any
apparent cause one of the smbd child processes has started to badly leak
memory (approx. 10Mb / minute) and possibly busy waiting, persistant across
reboots. The server has been running flawlessly in production for over three
months and absolutely nothing has changed on the server since it went into
production.
In my setup samba is PDC, with security=user, map to guest = Bad User and a
share with guest=ok. The runaway process is serving a guest user that is
accessing a single 2.5KB text file few times a minute.

I have a debug 10 log file as well as a kernel trace, if it is of any help.
Can anyone give me a hint on where to start looking? I have tried 3.0.20b
and 3.0.13 as well, and both gave me the same problem.
Regards, Mitja
