I seem to have solved the problem at least temporarily through this solution :
I installed the latest JDK on the deployed machine and ran tomcat
through catalina.sh debug, then "run"
No crash so far so good.

I might try tomcat 7 later too to see if it solves the issue....

Thanks for all the tips everyone
