Hi all,
I have a question about memory usage and IPC$ share.
I'am auditing the swap usage of my server because I already have a problem
with a full swap.
I see that the smbd process take < 200Mo on swap :
Example :
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
24429 lge 15 0 197m 39m 14m S 0.3 1.0 0:15.17 smbd
but some process use more than 200Mo
4923 ipcsrv 15 0 282m 121m 16m S 10.3 3.1 6:27.57 smbd
and I see that use user is ipcsrv, the "guest user".
If I do a smbstatus | grep 4923, I can see that the IPC$ is used :
[root at coradm01-node1 ~]# smbstatus | grep 4923
4923 jld Utilisateurs m557 (10.217.6.3)
jld 4923 m557 Mon May 10 07:59:30 2010
IPC$ 4923 m557 Mon May 10 08:38:07 2010
groupes 4923 m557 Mon May 10 08:38:00 2010
IPC$ 4923 m557 Mon May 10 12:32:30 2010
anyone can explain me how this IPC$ can appear ?
Samba 3.3.10
RedHat Enterprise Linux 5.3
thanks

They are very large. Can you run smbstatus 24429 pool-usage and post the output somewhere? In case, process "24429" does not exist anymore, please replace this number with the process id of a large process. Thanks, Volker
Yes, I can.
Can you look the file, this is the output of the command smbcontrol 24429
pool-usage -t 60

It might timeout. Try
smbcontrol 24429 pool-usage -t 60
> If I execute the same command for the PID 19080, I have data
Can you show us the data?

Can you try upgrading to 3.5.2? Alternatively, if your packages are official RHEL 5.3 packages, you might want to contact RedHat for support.

Volker,
OK
I take note, I will plan to update samba to samba 3.5.2.

I have recently commissioned a box running RHEL5.4 and samba sernet 3.5.2 that is AD integrated. The other shares on the box seem to obey the "inherit acls" and "inherit permissions" flags as well as "force create mode" and "force directory mode", but not on the _homes_ directory. Has anyone experienced similar problems, and where should I start looking to troubleshoot this problem? Thanks, Andrew
