TCP connections on Cisco ASA disconnects the database session every 30 Minutes


Right after a firmware upgrade form 8.4.2 to 8.4.7   on our ASA 5540:

the database app that makes a tcp connection with the database  loses connection to the database servers on the inside of the firewall

-Nothing changed on the process servers.

-Nothing but firmware version changed on the firewalls.

-Rebooting did not help.

-Connections don't always drop every 30 minutes, but it's still almost exactly at that time, with a 90% chance of it happening. And it reestablishes in about 52 second

-The client is not willingly terminating the connections to the database servers on the inside. The connection is just going away.

Are you using SQL inspection

Are you using SQL inspection?
Other user had same issue with Oracle DB and ASA 8.4(7) combination.
The workaround is to disable SQL inspection. Could you try this?

If the issue is still seen, pls contact Cisco TAC.
