Hi,

We have a few web applications with Security and Messaging EJB.
Works fine on several servers, but this particular server crashed after
a power failure about a month ago (may or may not be related).
We restarted it and it seem to work fine, but yesterday we saw a
messaging problem, so I checked server startup log
and found that both EJBs fail to deploy (no recent changes in configuration).

I am looking through the log, in addition to the few regular errors
(e.g. ?port already in use?),
we had a few strange ones prior to MessageCenterService EJB failed to deploy:

[1:] WARN [ServiceController] Problem starting service jboss:service=invoker,type=jrmp
java.rmi.ServerException: Could not bind JRMP invoker; nested exception is:
java.rmi.server.ExportException: Port already in use: 4544; nested exception is:
java.net.BindException: Address already in use
?..

[2:] INFO [STDOUT] Server.run/init: java.sql.SQLException: File input/output error: /Volumes/pkgs2/jboss-3.0.7/server/default/db/hypersonic/default.backup

That is a part of JBoss, why would it fail? (appman has no permission to read that file)?

[3:] That seem to be a JBoss service for EJBs

[4:] Another EJB service failing:

What might be causing such problems ?
Any help is very appreciated (I am pretty new to EJB and JBoss).

Thank you in advance,
Oleg.
