Tomcat 64 bits memory problems.

We have one opensuse 10.3 32 bits running tomcat without any problem. Another machine has the same OS but 64 bits. The two machines has the same code, same java, same -Xms and -Xmx java initializations, etc, etc, etc. Also, the hardware is the same.
The problem:
While 32 bits machine runs fine all the time, the 64 bits machine needs a quasi continuous tomcat restart, because java’s out of memory problems.

Anybody know if there are any difference between 32/64 bits java/tomcat? Maybe the 64 bits needs more memory?

Thank you and please, excuse me my bad english…

Have a nice day :wink:
