Re: Auto restart by DAS/node agent?

Hi Anissa,

Thanks for the reply.

But that doesn't quite seem to explain what I'm observing.

Basically, we had a clustered Glassfish instance throw an OOM for PermGen.

Almost immediately after that, the DAS / node agent automatically restart that instance. I see the following in the node agent log file:

[#|2010-05-06T12:12:19.773-0700|INFO|sun-appserver2.1|javax.ee.enterprise.system.nodeagent|_ThreadID=27;_ThreadName=Thread-24;|server espnbar16-sMlbGf has admin channel status of not running and desired status of running|#]

[#|2010-05-06T12:12:21.851-0700|INFO|sun-appserver2.1|javax.ee.enterprise.system.nodeagent|_ThreadID=27;_ThreadName=Thread-24;espnbar16-sMlbGf;|NAGT0017:The ProcessManager is restarting the server named espnbar16-sMlbGf|#]

This isn't bad behavior (I actually like it :-) but I would like to get insight into how often it's happening w/o having to comb through logs.

is there documentation anywhere on this feature and any customizable behavior it may have?
