Re: heap size params on linux
I think that any option you want to pass to the jvm can be placed in JAVA_OPTS, like this: set JAVA_OPTS = "-Xmx1536m -Xms1536m -server" I do that and it works fine. Rodrigo Stephen Charles Huey wrote: I see that JAVA_OPTS is mentioned in there quite a few times, so where exactly can I put set JAVA_OPTS=-Xmx1536m? Also, do I need to do both the initial and max in one line? E.g. set JAVA_OPTS= -Xmx1536m -Xms1536m (with nothing on the end of the line?) Does the -server option go with JAVA_OPTS as well?

Re: JVM Crash
Hi Wade, thanks for your reply. I already reported the bug, but they can take a long time to send an answer. Searching the bug database I found some posts that reported the problem happening with the client vm as well. I am considering trying another vm. I've just tested BEA JRockit 1.4.2_05, but it seems that Jira doesn't like it that much, or vice-versa : ) So, does anyone has experience with Tomcat 5.0.x running on JDK 1.5? Are there performace/stability issues?
