#3 Asyncronous read on dual core

[SOPC]

I am using java1.6 on dual core system.

When i run the application in synchronous mode... works perfectly and never fails.

Same code i run using asynchronous mode..
Works but get's terminated after some time...
Generating pid file in tomcat log.

My question is Is this code is tested on Java1.6 and dual core system?

If it is yes then is have to review my code (I have done this at least 100 times)

Thanks
