32bit Tomcat on 64bit RHEL - Maximum heapsize ???
 

Hi Gurus,

I have running 32bit Tomcat on 64bit Redhat machine. What is the maximum Xms Heapsize for 32bit applikation working in 64bit environment.

Today I saw that my Tomcat swapping. Seems to bee problem with memory. Does anyone could tell me what kind of heap size should I use ?

The highest theoretical limit of any 32-bit application is 4GB (2^32), but Tomcat could be limiting things below that threshhold. I've seen other JVMs where the limit is 2GB for a 32-bit implementation.

If you're going to 2GB as your initial heap size, I'd say you need to go to 64-bit.
