We have been running jboss 3.0.x for quite some time without any problems. Switching
to 3.2.3 we have a JMS problem. I don't know if there is a configuration file change
or if our application is doing something wrong.
The problem is that in {SERVER_HOME}/data/hypersonic, the localDB.data file
continuously grows. It never seems to shrink. We send a LOT of Messages to an MDB
and the messages are persisted temporarily until handled. That seems to work just
fine but the localDB.data keeps growing even when the messages are finished being
handled. The file eventually reaches about 2.0 gigs. At that point, JBoss starts
throwing lots of exceptions.. example:
Could not store message: 11175 msg=11166 hard NOT_STORED
PERSISTENT queue=QUEUE.EmailQueue priority=4 hashCode=20379376; - nested throwable:
(java.sql.SQLException: S1000 General error java.lang.NullPointerException in
statement [INSERT INTO JMS_MESSAGES (MESSAGEID, DESTINATION, MESSAGEBLOB, TXID, TXOP)
VALUES(11166,
.... .... ...
The only solution has been to kill the jboss processes, delete the hypersonic
directory, and then start again, letting hypersonic create a new empty database.
Is there any way to automatically shrink the database?
We are using the default configuration without any customization other than deploying
our application. I can connect to the hypersonic db and verify that there are no
records in the JMS_MESSAGES table but the file is still ever growing.
OS: Linux 2.4.19 kernel
JDK: Blackdown jdk 1.4.1
JBoss: 3.2.3
Thanks for any input.
