the way i see it the wrapper is a process and the jvm is another. when the kill signals go around, they go directly to all processes. that explains why one process dies but not the other. i'm with you on the second question. why isn't the wrapper restarting it? could the intermediate/daemon processes be in an inconsistent state if they manage the jvm pinging? that'sall i got -----Original Message----- From: wra...@li...

Subject: RE: [Wrapper-user] wrapper executable fails to restart JVM I'm not sure how this is related. When the JVM dies, if you *are* using the wrapper, shouldn't the wrapper restart it? -----Original Message----- From: Sal Ingrilli [mailto:sal...@sy...] Sent: Monday, January 05, 2004 12:00 PM To: wra...@li... Subject: RE: [Wrapper-user] wrapper executable fails to restart JVM 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.
