[Samba] Samba memoeur usage and IPC$

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@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
