Well, before blamin gthe JVM completely, as we have never had this problem with all incarnations of the JVM, try running your site on various open-source choices to make sure its not JRun. Use Orion (www.ironflare.come), JBoss/Jetty (www.jboss.org for the combined jboss/jetty release), JBoss/Tomcat (same url), and Tomcat by itself, as well as Jetty by itself. Resin is another one (www.coucho.com I think). These are all pretty simple to configure to run an app, although expect to spend a little time for each. Then, run your app and see if you get the same errors. If you are still getting them, there are a few things you can do. As you suggest, go back to an earlier version, and if it works, use it. Also, I would look at upgrading your OS to Win2K if your on NT. It is not a requirement, but I haven't used NT in quite some time and am not having these issues, with JRun, WebLogic, Orion, Jetty/JBoss, or Tomcat. We now use Jetty/JBoss, still no problems.
Worse case, reinstall your OS, then try it again. That always sucks, but you never know..perhaps some other app you have installed is conflicting with the JVM. Also, make sure (although doubt this would or should be the problem), that other apps using the JVM are not running, and make sure while on WinX/NT/2K that you are infact using your JDK, and not the JVM installed by Windows, which was a little buggy and out dated.

But I use WinXP Professional, and everywhere I look, I got JVM/JDK error messages with the latest release from Sun (i.e. 1.3.1.02)... everywhere I looked. I uninstalled that, and installed 1.3.1.01 and have never gotten any error messages since. The messages including MSIE crashing visiting Moviefone.com and any web-based java applet-containing website. (PS: Opera browser urges the latest JVM/JDK, but that browser seems to only work with 1.3.1.02 as well... so I stopped using it until Sun fixes these Win32 issues.)

It is a large site with many JSP files and beans.) We are experiencing these significant problems: - Browsing through our JSP pages often results in a JVM crash (a bad one!). We get "javaw.exe - Application Error Access Memory Violations ...Instruction referenced memory ...." which is caught by Dr. Watson. This seems to happen after the JRun has been running several hours but scouring the log files has not yielded any specific JSP page which could be causing the problem(seems to be random). From the server console, we see drwatson dialogue box with the "javaw.exe" error and the "dontdiejava.exe" error which indicates that the memory contents are being dumped to a 500MB dump file. - Sometimess we see a "java.lang.OutOfMemory <<no stack trace available>>" error in the JRun log files (but not every time the JVM crashes). From the browser we sometimes get an OutOfMemory error as well. Not sure if the OutOfMemory exception is related or not. This may be a separate problem which also causes the JVM to crash - We've seen these error messages in the log file occassionally: # # HotSpot Virtual Machine Error, Internal Error # Please report this error at # http://java.sun.com/cgi-bin/bugreport.cgi # # Error ID: 4349254E560E43505000F4 # # Problematic Thread: prio=5 tid=0x449ad0 nid=0x57 runnable # # HotSpot Virtual Machine Error, EXCEPTION_ACCESS_VIOLATION # Please report this error at # http://java.sun.com/cgi-bin/bugreport.cgi # # Error ID: 4F533F57494E13120E43505002D4 # -These problems have been reported to Sun but they have only recommended upgrading the JVM to 1.3.1.02 or 1.4Beta since we cannot identify an exact causal sequence Any suggestions? Anyone had similar behavior? __________________________________________________ Do You Yahoo!? Great stuff seeking new owners in Yahoo!
