timeout after long waiting

Could someone assis to solve this?

[2006-02-08 18:01:30 SGT] <WorkerThread5> <WOWorkerThread id=5 
socket=Socket[addr=/192.168.0.24,port=2213,localport=55558]> Exception while 
sending response: java.net.SocketException: Software caused connection 
abort: socket write error

It happens when I have invoked an action in WOComponent, and the action 
takes a bit longer time to process (still less than 2 minutes).  Before the 
process is ended, the browser had already gone into error page.  The session 
timeout is much longer than the processing time.

Appreciate any input.  Thanks.
