Error reading from fd 30

Hi there,
 
I just wondered under what circumstances, I should be getting the following
errors:
 
2004-04-16 16:26:54 [1] ERROR: Error reading from fd 30:
2004-04-16 16:26:54 [1] ERROR: System error 104: Connection reset by peer

2004-04-16 16:26:54 [1] ERROR: Error reading from fd 30:

as thread [1] is:

Will post logs,etc if need be. I am running a CVS version from february at
the moment - will update and see if the same problems occur.
