pserver - getting down

[Kudiyarasan]

Hi ,
    I have two  issues :
1 . <cvs rdiff> uses <diff -c> by default . But how to get <diff>
simply  without -c option .

2.  When I use  <cvs log> or  <cvs diff>  for  a module having nearly
1000 files , pserver is getting down .
Message is shown like the following  at the middle
      cvs [log aborted]: connect to nms-build:2401 failed: Connection
refused
 How to overcome this ?

 Thanks & Regards ,
