Over the past 2 days, my smbd processes are multiplying worse than
rabbits. At least with rabbits it's easy to tell why you wind up
with so many...
Here's the setup:
Samba version 3.2.8-0.24 installed via rpm on a FC6 box with 2 nics,
both on the same subnet. The samba server acts as a PDC in a mixed
environment but mostly windows pc's running xp. It is used mostly
for file (Quickbooks) and print services.
We have a small home business network with usually only 3 accounts
connected, and no more than 10 open files at any given time. I
noticed yesterday that I was having trouble logging in from one
machine - share's not available, etc. So I checked the daemon to
make sure that it was running an lo and behold - there were over 400
instances of smbd.
It took two attempts to stop them all from the init script - the
first run seemed to only kill about 2 or 3 and the second one
finished the job. So I restarted and monitored the situation and all
seemed okay for a few hours and then after about 3 hours they started
multiplying again until I restarted the daemon again. There was just
normal file activity during the couple of hours that it took to go
from 3 to over 400 pid's.
I increased the log level to 3 but all I am seeing is the normal
wins, nmbd connections. I am seeing a few errors but nothing
significant I don't think - tell me if I'm wrong - but nothing in
these log files that correlate to the timing of the runaway processes:

You might want to strace -p <smbd-pid> some of the smbds and send the output. You might also want to see what process state according to ps the smbds are.

The samba server acts as a PDC in a mixedPlease explain your reasons for using two NICs with IPs on the same subnet and how you make sure packets sent out through one interface don't get their replies routed through the other.

I'd suspect that it's a socket where the other end is dead for some reason. If you can figure out what daemon is on the other end, you might try to restart it.

Maybe you find another "0xf1fd4000" in lsof?Since I wrote last night I restarted smbd and it was okay for about 12 hours. And then: # /sbin/service smb status smbd (pid 18249 18060 18051 18041 17661 17656 17652 17543 17522 17514 17357 17353 17346 17345 17339 17336 13300 12984 12958 12957 12712 12384 12379 12342 12005 11973 11968 11870 11842 11839 11723 11717 11714 11482 11480 11475) is running... nmbd (pid 11478) is running... I found a couple of things. The first smbd started has a couple of sockets: smbd 11475 root 21u unix 0xdb59ba00 3225813 socket smbd 11475 root 22u unix 0xdb59be00 3225814 socket smbd 11475 root 25u unix 0xca340200 3225816 socket 11480 - no sockets 11482 - smbd 11482 root 23u unix 0xed4c1400 3225837 socket 11714: smbd 11714 root 21u unix 0xdb59ba00 3225813 socket smbd 11714 root 22u unix 0xdb59be00 3225814 socket smbd 11714 root 25u unix 0xca340200 3225816 socket 11717: smbd 11717 root 21u unix 0xdb59ba00 3225813 socket smbd 11717 root 22u unix 0xdb59be00 3225814 socket smbd 11717 root 25u unix 0xca340200 3225816 socket and on up the list all have the same three. I did notice this though as I was looking at the lists not sure if it means anything. The machine is a Mac PB5 : # /usr/sbin/lsof | grep pbg5mac smbd 12957 root 6u IPv4 3927677 TCP yoda.wrenkasky.com:netbios-ssn->pbg5mac.wrenkasky.com:52093 (CLOSE_WAIT) smbd 12958 root 6u IPv4 3927823 TCP yoda.wrenkasky.com:netbios-ssn->pbg5mac.wrenkasky.com:52094 (CLOSE_WAIT) smbd 12984 root 6u IPv4 3928044 TCP yoda.wrenkasky.com:netbios-ssn->pbg5mac.wrenkasky.com:52095 (CLOSE_WAIT) smbd 17336 root 29u IPv4 4022743 TCP yoda.wrenkasky.com:netbios-ssn->pbg5mac.wrenkasky.com:52103 (CLOSE_WAIT) smbd 17339 root 6u IPv4 4022891 TCP yoda.wrenkasky.com:netbios-ssn->pbg5mac.wrenkasky.com:52107 (CLOSE_WAIT) smbd 17345 root 6u IPv4 4023050 TCP yoda.wrenkasky.com:netbios-ssn->pbg5mac.wrenkasky.com:52112 (CLOSE_WAIT) smbd 17346 root 6u IPv4 4023164 TCP yoda.wrenkasky.com:netbios-ssn->pbg5mac.wrenkasky.com:52114 (CLOSE_WAIT) smbd 17353 root 6u IPv4 4023360 TCP yoda.wrenkasky.com:netbios-ssn->pbg5mac.wrenkasky.com:52116 (CLOSE_WAIT) smbd 17357 root 6u IPv4 4023506 TCP yoda.wrenkasky.com:netbios-ssn->pbg5mac.wrenkasky.com:52117 (CLOSE_WAIT) I restarted again as communication with smb was timing out. I keep searching the archives of this list and the Internet but have not found a whole lot that relates directly to this issue and the things I have tried so far have not fixed it obviously.

You need to scan for 0xdb59ba00 (or whatever it will be next time), and find the non-smbd process that holds this socket. Restart that one or don't start it at all.
