Hi there
I'm still in the process of assessing an application which make a fairly
heavy use of mina. It is packaged as a webapp deployed under tomcat.
Using netstat I have noticed a strange (to me) connection pattern like the
one attached below. I understand that this is very application specific and
that it's hard to draw conclusions just looking at this trace, but this
application itself doesn't open internal connections this way: it is
basically a bunch of acceptors and connectors, so nothing that would explain
a netstat output like this. Moreover, I have used a sniffer to inspect
traffic but I haven't captured any of it. Strange.
Does anybody have ever noticed something like this? The server running this
application has shown to sometimes to run out of resources (not being able from
the system nonpaged pool and thus not being able to create any more
connections) and I'm trying to get to the cause. I have been monitoring the
trend of these connections and they seem to enlarge and shrink but
definitely they show a steady growth. Still, I don't know who's opening
them. I hope you guys can help:)
Btw, production is still running 2.0.0-M6.
First thing I would do would be to switch to MINA 2.0.2. 2.0.0-M6 is
just totally outdated.
