Thank you for the continued followup!
Here is what I see with -trace. First time, all good. Second time, no tcp
server. I have upgraded the jar to the .174 version (h2.jar is a symbolic
link):
and downgraded java slightly (We can't go back to 1.6; maybe better to
upgrade to latest instead and try that):
java version "1.7.0_25"
Java(TM) SE Runtime Environment (build 1.7.0_25-b15)
Java HotSpot(TM) 64-Bit Server VM (build 23.25-b01, mixed mode)
Also attaching thread dumps...but really it just shows what we know:
sometimes the TCP (and PG) server fails to start.
Is/could it be a networking problem? I don't see how. We are all on
localhost here and once the server is running correctly, we never have
problems. The intermittent problem is all about the start up. It appears I
can just restart until I get it right, but this is not an answer to the
problem.
