Also remember that for each thread created on the JVM it will create a thread on the OS.
We had that problem and now our servers are running with 1408 MB of memory but with the IBM JDK 1.5. Here are some settings -Xrs -server -XX:SurvivorRatio=8 -XX:PermSize=128 -Xmn128m Initial memory 1408mb Max memory 1408mb Trhead stack size 128kb I don't know about Java 16 yet but these settings are working really good. -----Original Message----- From: alvaro tovar [mailto:[EMAIL PROTECTED] Sent: Monday, July 16, 2007 4:41 PM To: Tomcat Users List Subject: Re: About Using memory JVM and Tomcat Christopher Schultz say. Most 32-bit JVMs can't actually give you 3GB of heap space. You'll probably be limited to somewhere between 1.5 - 2.0GB. If you have a 64-bit processor and OS, go with a 64-bit JVM and then you can get /lots/ of memory.
