It seems really unclear what all of this has to do with Tomcat.
Tomcat is Java code. It runs under a JVM, and uses that JVM's code for anything to do with

the interface to the underlying OS or hardware.  So it should not make an iota of 
difference to Tomcat under which OS and machine it is running.
On the other hand, the /JVM/ which you are using may have problems, but again that has 
nothing to do fundamentally with Tomcat.

Then provide the new log, or do you just want us to keep guessing ?
