Hundreds of connections to port 1701 (Hypersonic db?)

[doc_brown]

I've noticed that one of our machines has an ever increasing amount of connections to port 1701. This machine is mainly used to handle JMS.

We do have an app running on this machine that submitts (and receives) messages from the JMS.

There are presently 915 open connections to /from this port. A sample of the connections:
127.0.0.1.1701 127.0.0.1.59508 49152 0 49152 0 ESTABLISHED
127.0.0.1.59509 127.0.0.1.1701 49152 0 49152 0 ESTABLISHED
127.0.0.1.1701 127.0.0.1.59509 49152 0 49152 0 ESTABLISHED
127.0.0.1.61492 127.0.0.1.1701 49146 0 49152 0 ESTABLISHED
127.0.0.1.1701 127.0.0.1.61492 49152 0 49152 0 ESTABLISHED
127.0.0.1.61493 127.0.0.1.1701 49146 0 49152 0 ESTABLISHED
127.0.0.1.1701 127.0.0.1.61493 49152 0 49152 0 ESTABLISHED
127.0.0.1.61494 127.0.0.1.1701 49146 0 49152 0 ESTABLISHED
127.0.0.1.1701 127.0.0.1.61494 49152 0 49152 0 ESTABLISHED


Anybody know why it would seem that the Hybersoinic DB is doing all this talking to it self?

I'm running Jboss 3.2.1 on Sparc/Solaris 9
java version "1.3.1_07"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1_07-b02)
Java HotSpot(TM) Client VM (build 1.3.1_07-b02, mixed mode)

This is the second report I've seen in a couple of days. You may want to check the JBoss SourceForge site and see if anyone has logged a problem report on it and perhaps log it if there isn't an existing report.

I haven't noticed the issue because we run hsqldb in an in-line mode that doesn't enable the port. This might be a workaround for you in the meantime.

If you look at the hsqldb-ds.xml you can run with this configuration:
<connection-url>jdbc:hsqldb:default-db-name</connection-url>

You can then also disable the HypersonicDatabase MBean. There is a third configuration that runs the DB totally in memory. The DS config is well commented.
