JBoss slow startup time - pauses right after Core system initialized

[Mike Curwen]

Hi,

We're moving a production server over to VM infrastructure. I've confirmed that all components (java, jboss, application and libraries) are the same between platforms. I've also made the platforms as close as possible (same HD, same RAM, better CPU). The difference would be that our existing production server is an old stand-alone server, running linux 2.6.8 ( I think some flavour of redhat) and the new production instance is a vmware host. Not sure what the server is, but the host OS is ubuntu linux 2.6.24

I recognize that there's quite a difference between plain hardware and VMWare hosts. But...

When I start this application on my localhost for development it takes about 17 seconds for the whole thing to start. On production it takes about the same. But on the new VM host, it takes a minute and 17 seconds, and nearly the whole minute extra is experienced right here (3rd line from bottom):

See how after "Core system initialized', it pauses for nearly a minute?

Anyone seen this, or have ideas what the cause is?

Deja vu!

For the benefit of the ranchers, here's the discussion we have had so far on the JBoss forum:

I suspect that Mike is looking for opinions or suggestions other than the ones already made.
