Hi,

I tried to see how to reproduce that problem I did face, shortly the
problem was Glassfish (last version)hangs after a heavy load on Virtuozzo
VPS.

1) I couldn't actually reproduce the problem on my localhost with the
simple web app
2) I couldn't actually reproduce the problem at another VPS (the same
provider Hosteurope and same VPS generation 5.0), running another non-DB
app, neither DB app

*Which means that I couldn't actually reproduce the problem using different
app / similar VPS. *

In that case I cannot actually file the bug, since I cannot write the steps
to reproduce the problem, therefore I don't think Oleksiy that you can do
much about it.

Honestly, now it looks to me that it was more kind of Kernel TCP settings
(under given Virtuozzo VPS instance) - Application Connection Usage problem
rather than Glassfish problem.

Thank you for your time,
Mladen
