My Tomcat is running on 32-bit Red Hat 4 (2.6.9-78.0.1.ELsmp), host server has 8G physical memory and 4 processors. java version "1.4.2" gcj (GCC) 3.4.6 20060404 (Red Hat 3.4.6-10) I got java.lang.OutOfMemoryError Current configuration: -Xms1024M -Xmx2304M The host server has about 4.5G free memory. When I tried to increase -Xmx2304M to -Xmx3000M, I got this error: Error occurred during initialization of VM, Could not reserve enough space for object heap The maximum # I can reach is -Xmx2680M. QUESTION: Is there an upper limit for -Xmx? What is the work around? How can I use my free memory on the server to get rid of the OutOfMemoryError?
Thanks, Henry
