qpid-tool list says 500 connections (4 clients), is it ok?
The problem is that I can't connect to the broker with other clients after a
while.
The list command of qpid-tool shows the following:
qpid: list
Management Object Types:
ObjectType Active Deleted
======================================================
org.apache.qpid.broker:binding 31 0
org.apache.qpid.broker:broker 1 0
org.apache.qpid.broker:connection 500 0
org.apache.qpid.broker:exchange 6 0
org.apache.qpid.broker:queue 15 0
org.apache.qpid.broker:session 2 0
org.apache.qpid.broker:subscription 5 0
org.apache.qpid.broker:system 1 0
org.apache.qpid.broker:vhost 1 0
I have only 4 clinets to my server. Is it ok to have 500 connections for thees
or am I doing something wrong ?
Also the command qpid tool `list connection` shows a BIG BIG list like:
:
:
:
648 12:09:29 - 103.10.10.8.127:7311
649 12:09:31 - 103.10.10.8.127:7312
650 12:09:34 - 103.10.10.8.127:7313
651 12:09:36 - 103.10.10.8.127:7314
652 12:09:38 - 103.10.10.8.127:7315
653 12:09:41 - 103.10.10.8.127:7316
654 12:09:43 - 103.10.10.8.127:7317
655 12:09:45 - 103.10.10.8.127:7318
656 12:09:48 - 103.10.10.8.127:7319
657 12:09:50 - 103.10.10.8.127:7320
658 12:09:53 - 103.10.10.8.127:7321
659 12:09:55 - 103.10.10.8.127:7322
660 12:09:57 - 103.10.10.8.127:7323
661 12:27:17 - 103.10.10.8.127:7378
662 13:34:40 - 103.127.0.0.1:60364
Is it possible that I open too many connections and don't close them.

There's a qpidd configuration option "max-connections" which is set to 500 by
default.
--max-connections N (500) Sets the maximum allowed connections
You can set it to a higher value

I am using the c++ 0.6 client on windows.
Indeed, I was not closing the connections.
Thank you for your assistance.

That *could* be a result of
https://issues.apache.org/jira/browse/QPID-2636 (now fixed on trunk but
present in 0.6).

That's also possible of course. Is it possible that you aren't closing
connections? What client(s) are you using?
