RE: XP random tomcat crashes
We normally use the server jvm, but have also seen the crashes with the client. Any ideas?

RE: XP random tomcat crashes
Hi David, The following might be of use to you: We recently had a struts-based application that crashed seemingly randomly, and after a lot of work and debugging we tracked it down to a bug in the JVM (we were using Sun's 1.4.1 JDK ). It was reproduceable on several platforms (HP-UX, Linux, win2k). We were not getting any dumps either on some of the platforms, the process seemed to just hang. Note: testing showed IBM's JDK didn't exhibit this behaviour, but Blackdown did. A workaround for us was to add the following parameters to Sun's 1.4.1 JVM: -Xint Operates in interpreted-only mode. -XrsReduce usage of operating-system signals by Java virtual machine (JVM). A fix for us was to upgrade to JDK 1.4.2 For more info, try posting the VM messages you are receving here. They may not be very helpful to you (or me:-) but perhaps somebody knowledgeable on the list might be able to make sense of them.

RE: XP random tomcat crashes
Howdy, I would only offer the usual advice: - Get the latest stable JDK (1.4.2) - Get all the patches for your OS - Get the latest stable tomcat (4.1.27) - Start the VM with no switches and observe behavior, i.e. stick to default client mode Personally, I had problems with 1.4.1 in server mode on solaris that all went away (without significant performance degradation) when I stopped using the -server switch. YMMV.

From: dhay () lexmark ! com We're using tomcat 4.1.12 with Java 1.4.1.02, and are encountering strange crashes on XP especially. The crashes happen in apparently random places in our app, and cause the VM to crash with various messages, none of which are very helpful! I noticed that Cameron Hart had a similar problem (http://www.mail-archive.com/[EMAIL PROTECTED]/msg88603.html) Just to be clear, this is a crash in the jvm itself (native code), as opposed to say an unhandled Throwable (in java code)? Historically, the jvm would usually generate a file whose name began with hs_err_pid. You might look for one of them (try the vm's current working directory, or java.io.tmpdir). On that level, your first bet might be to start looking for similar problems in Sun's bug database. http://developer.java.sun.com/developer/bugParade/index.jshtml -- Steve - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
