[Samba] Samba4 spawns many /usr/sbin/smbd --configfile
I have no idea why, occasionally one of my samba4 servers won't respond to my RSAT tools on windows 7. I check the server and when I do a ps -aux I see many lines just like the following: root 28073 0.0 0.0 2132 52 ? S 00:11 0:00 /bin/sleep 999999999 3000063 28176 0.0 0.4 87604 7144 ?

I'm using samba4 beta6 I believe on this machine.

S 00:11 0:00 /bin/sleep 999999999[...] This indicates that Samba has crashed and has called "sleep 999999999" as the panic action. This is to allow you to attach a debugger to the parent process and get a stack trace (assuming you compiled with ./configure.developer). You should be able to do something like this: Use "ps axl" to get the parent process ID (PPID) of one of the sleep processes. (e.g. 12345) Then: # gdb /usr/local/samba/sbin/samba (gdb) attach 12345 (gdb) bt full That might tell the Samba developers what caused the crash.> I usually just reboot that server and it's all good again. > > I'm using samba4 beta6 I believe on this machine.Run /usr/local/samba/sbin/samba --version to get the exact version. -- Michael Wood <esiotrot at gmail.com>
