Thanks everyone. The solution to this is relatively quick and simple. Glad to see I'm not going crazy. :-) David On 2012-02-04, at 6:15 PM, Mike Schrag wrote: > Also check if you're overcommitted on ram with your jvms. That could manifest > as the vm dying at startup if it can't claim Xms w

Also check if you're overcommitted on ram with your jvms. That could manifest as the vm dying at startup if it can't claim Xms worth of memory. Sent from my iPhone On Feb 4, 2012, at 8:51 PM, John Huss wrote: > I think that would depend on how many servers are running the instances. > > On Sa

I'm not sure - but - that's an odd number, but why don't you have separate servers for more instances? are you trying to increase the number of threads to your database?. seems like 8 instances is more of a heavy load/normal situation - 50 instances sounds like maybe a mistake in approach?

Limit to the number of instances under JavaMonitor

2012-02-04 Thread David Holt
Does anyone know if there is a limit to the number of instances you can run under JavaMonitor? Is it a fixed limit, or a configuration? I seem to have hit it. My new instance dies silently. No log, just a new "Death". I can start the application from the command line. After trying everything I
