Hi guys,
from time to time Jboss seems to be closing the connection with my Interbase db.
The message I get in the Jboss log is:

[XADataSourceLoader] Stopping
[cywDS] XA Connection pool cywDS removed from JNDI
[cywDS] XA Connection pool cywDS shut down
[XADataSourceLoader] Stopped

Anyone has a clue about what might be going on?
Thanks
