at my old job we never ran the wrapper but we did run java/weblogic. our java process would simply die for no reason, and even simultaneously across networks! we had one network in NY running production & one in CA running qa. servers in both time zones would die simultaneously. we were going crazy & did a ton of research. after weeks of dealing with weblogic, we got escalated to a tech who told us to run the java process with NOHUP. so instead of running java MyApp run nohup java MyApp nohup is unix utility that ignores kill signals from the OS. -----Original Message----- From: wra...@li...

Subject: Re: [Wrapper-user] wrapper executable fails to restart JVM To follow up with a little more info in case it's of any use. We've been running duration tests with the debug output on, on a number of boxes for two weeks, but haven't seen this problem on any of them. We recently reinstalled the application on one box but forgot to turn the debugging output on, and of course 21 hours later the JVM process was gone. The log snippet from the previous email is from that failure. We've now turned debugging on again, but it's not clear whether we can reproduce the problem with debugging on. --- Patrick Woodworth <wo...@em...> wrote: > I'm using the wrapper to run a service and I'm seeing odd behaviour > on > two Solaris 8 boxes.
