[Samba] samba performance degrade

dear all
  I am using samba 3.0.28 on RHEl 5.2. I am using samba with winbind 
that authenticate window 2003 domain. From last few months samba was 
running properly. But today samba server performance badly, even 
sometime mapped drive on xp disappear. When i tried to connect samba 
shares, error appear server not available. Anyone suggest me what may be 
the problem. Why samba performance degrade after running around a month.

my configuration is as follows

[Samba] samba performance degrade

have you ruled out a networking problem? (i.e. Switch didn't auto-neg to the
