It pushin' up daisies I tell you... Pinin' for the fiords..
We shut down the database for a backup at 8:00 on Sunday (I was supposed to stop JBOSS at 8:00 as well but my crontab did not work (needed a * for the day??)
Any JBOSS keep running writing to the log database comes back up.
Then Sunday just before midnight JBOSS stops writing to the logs.
Then requires a JBOSS shutdown and Restart.
Does this make sense happening when the database goes down without JBOSS going down?
For any input you can provide.
Dificult to say what happen. You should check the logfiles and maybe a thread dump, heap dump and GC loging.
If you shutdown the DB the connection pool should try to close failing conections and open new ones if the DB is back.
