[Samba] Samba memoeur usage and IPC$

[Stéphane PURNELLE]

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
