[Samba] Broken pipe errors

[Julie Catellier]

We have samba version 1.9.18 on Solaris 5.  This has worked well 
and suddenly we were unable to log in or gain any access to the 
samba shares or to the server itself because access was so slow. 
This problem has only happened for approx 4 hours today and last 
Friday.  We have the errors listed below.  Can anyone help us with 
this?
