All,
I'm running the latest stable version of SerNet-Samba on a Debian Sarge
box (I switched from the traditional Samba package for certain reasons
which I won't delve into here), but I've come across a serious issue.
Every day, the Samba processes become so numerous that the server begins
acting really flaky. That is to say, there are so many smbd -D
processes that the server stops responding to further Samba requests and
the server comes to a crawl. For brevity's sake, I won't post the
results of 'ps auxwww | grep smbd', as it would take up a lot of
unnecessary space...but an smbstatus reveals nothing that indicates a
huge problem:
server:/var/log/samba# smbstatus

I've tried *everything* short of strace-ing, and I'm running out of
options and time to get this working. If anyone has had similar
problems, please let me know what you did to correct the issue. Nothing
is NFS mounted, everything is local to the box (Samba, the home
accounts, LDAP, etc). It seems to me that Samba doesn't recognize when
an smbd process should be killed on the server side, so they continually
build up. However, memory usage and swap space usage on the box are
relatively low, so it's not an issue of the server being unable to
handle the load of traffic. Users then experience the problem of being
disconnected and working offline, being unable to print, unable to
access shares, etc. Also of note: If I enter at the command line the
following command: 'smbclient -L server -U username' when the server is
overflowing with smbd processes, I get the following error: session
setup failed: Call timed out: server did not respond after 20000
milliseconds. Any suggestions would be greatly appreciated! If you
need any further details, I would be happy to provide them.
Best,
Ryan
