I've posted the problem there some time ago: ----------------------------------------- I have a problem with samba 3.0.26a (from ports) on FreeBSD (amd64, SMP, 6.2 RELEASE).

Next I can see in the top a lot of run smbd processes. System load grows and smbd makes it unresponsible. Connection with ssh is impossible, I can only use (with problems) console. Command "killall -9 smbd" helps, system goes back to normal work. -------------------------------------------- Samba 3.0.24 doesn't produce such many processes and system is ok, but log.smbd is full od panic problems and SMB protocol doesn't work. -------------------------------------------- After killall sometimes "/usr/local/etc/rc.d/samba restart" is enough but sometimes it is necessary to clear all files from /var/db/samba/ and then run samba again... On 3.0.24 "/usr/local/etc/rc.d/samba restart" works ok. >How-To-Repeat: I'm not sure, but the problem repeats after every hard reboot - after shutdown on power loss :( >Fix: I'm not sure, but I noticed some things last time ... Problem is because system crashed and some files are damaged. After power loss system starts fsck to correct all fs problems. What is the filesystem state when backgroud fsck is running? Is it read only mode? If yes, maybe it makes the problem with samba start? It looks like samba problem. If filesystem is in read only mode, then maybe smbd start should be delayed? Is it possible to run "/usr/local/etc/rc.d/samba start" on system boot after fsck finishes? >Release-Note: >Audit-Trail: >Unformatted:
