I have experienced a similiar issue and was thinking it was most likely the JVM (SUN J2SE 1.3.0 Hotspot Server). Anyone had any luck with running Orion with JRocket. Looking at the Volano report(http://www.volano.com/report.html) it would appear to scale the best. I've attempted to run it with orion and had no success. IBM JVM also appears to scales better than the Sun JVM but I've had some stabilty issue when trying out this JVM, it gave up the ghost about every 4 hours on my machine. -----Original Message----- From: Karl Avedal [mailto:[EMAIL PROTECTED]] Sent: Tuesday, March 13, 2001 2:47 AM To: Orion-Interest Subject: Re: Orion Load Problems Hello Daniel, These kind of problems are indeed hard ones to solve, since they appear only under certain circumstances, but the load you specify is not something there should be a problem with. What you can do is try to change the VM options and try the 1.3.1 beta jvm to see if you see any change in the behaviour. You can also try the latest experimental Orion, 1.4.7 available via auto-update. If this is indeed caused by a bug in Orion, it's definately one that needs to be fixed right away so we'd be very happy if you could try another jvm to make it easier for us to locate what goes wrong. A temporary solution if it's extremely urgent, could also be to use load balancing and setting up a small cluster until we have located what's going on.
