We are using samba services for establishing connection btw Unix server & 
Windows 95 PC. Samba services are running at Sun Server. The issue is that all 
of sudden for unknown reasons samba client share  goes down. Root processes 
nmbd & smbd (with PID = 1) keeps on running. Here is one sample:
Following is the samba status, when there is a samba connection with 
PC "client123"
Samba version 2.2.8a
Service      uid      gid      pid     machine
----------------------------------------------
queue01      aradmin  remedy   11583   client123  (131.222.100.20) Sun Oct 19 
15:43:20 2003

& here are the samba processes :
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
root  1151     1  0   Oct 05 ?  0:00 /usr/local/samba/bin/smbd -D -s/u
sr/local/samba/lib/smb.conf
root  1156     1  0   Oct 05 ?  0:09 /usr/local/samba/bin/nmbd -D -s/u
sr/local/samba/lib/smb.conf
root  1162  1156  0   Oct 05 ?  0:00 /usr/local/samba/bin/nmbd -D -s/u
sr/local/samba/lib/smb.conf
root 11583  1151  0 15:43:18 ?  0:05 /usr/local/samba/bin/smbd -D -s/u
sr/local/samba/lib/smb.conf

When the samba share for client "client123" goes down then we don't have 
anything beneath samba status & the following process (last one)  processes 
heading get killed. samba processes still shows remaining 3 processes.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 
root 11583  1151  0 15:43:18 ?  0:05 /usr/local/samba/bin/smbd -D -s/u
sr/local/samba/lib/smb.conf. 
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Now-a-days samba is dropping share very frequently. Samba plays a critical role 
in our application. Any help in this regard will be greatly appreciated.
