Hello,
We are running Jonas 1.6.1 on Jeremie with Interbase 5.5 and Interclient
1.51
Our server sometimes just hang up and the processor is on 100% utilization
even
if nobody is doing anything. Last time this happened, I noticed following
output, which I assume came from Jonas
WARNING: Connection was not always closed correctly !
connection-open counter underflow
removeConnection: connectionlist is empty
Does it ring a bell? Have anybody seen something similar? ANy help is
greatly appreciated.
Regards,
Miroslav Halas

Yeah... It turns out that this may have cropped up because we moved all our
read only methods over to tx_supports... now the connection grabbing is
happening outside a transaction, so it is relying on us to be good
consistent
programmers, instead of letting us be sloppy and having the end trans clean
everything up. I suspect in most places we are clean, but we must have
missed
one.... I'm still a little skeptical though because it seems that if we run
through the same set of bean calls, we dont see a problem til we have
several
threads banging on it for around two hours... I'd expect to see something
right away if it was our code forgetting to close something....
I'm not ready to give up and say its our code yet because of this, our
current
theory is that it may be a multithreaded issue... but I'm also trying to
chase
down if we are fogetting to close a connection in our code somewhere or
closing it more then once....
