AwareIM crash

Hubertus

Hello,

my problem is that AwareIM sometimes stops working and restarting requires to replace the current JBoss directory with a fresh one. The last time this happend was 2 weeks ago and twice today.

The Tomcat log repeatedly contains

- Connection failure, use javax.jms.Connection.setExceptionListener() to handle this error and reconnect
org.jboss.mq.SpyJMSException: No pong received; - nested throwable: (java.io.IOException: ping timeout.)
at org.jboss.mq.Connection$PingTask.run(Connection.java:1278-)
at EDU.oswego.cs.dl.util.concurrent.ClockDaemon$RunLoop.run(ClockDaemon.java:364)
at java.lang.Thread.run(Unknown Source)
Caused by: java.io.IOException: ping timeout.
... 3 more

and the AwareIM server log repeatedly contains

FAULT: ERROR: org.openadaptor.adaptor.jms.JMSSink - txnCommit() failed with JMS Queue/Topic PublishException: org.openadaptor.adaptor.jms.PublishException: org.openadaptor.adaptor.jms.JMSPublisher - commit() failed with JMSException: org.jboss.mq.SpyJMSException: Cannot process a transaction; - nested throwable: (java.io.IOException: Client is not connected) [java.io.IOException: Client is not connected]
ERROR: transaction commit failed (will call rollback) , ERROR: org.openadaptor.adaptor.jms.JMSSink - txnCommit() failed with JMS Queue/Topic PublishException: org.openadaptor.adaptor.jms.PublishException: org.openadaptor.adaptor.jms.JMSPublisher - commit() failed with JMSException: org.jboss.mq.SpyJMSException: Cannot process a transaction; - nested throwable: (java.io.IOException: Client is not connected) [java.io.IOException: Client is not connected]

Any ideas on what could be the cause for this ?

This may happen if the Aware IM server is running on a machine where the IP address can dynamically change. For example, one of our development machines has Internet connection with dynamically assigned IP address. Whenever the ISP changes the IP address a crash similar to the one you experience occurs. Any possibility of that?

Hubertus

Could this also be caused by a DHCP renewal where the IP adress does NOT change ?
On some other thread I've read about troubles caused by a short interruption of the network. Would this show up the same way ?

aware_support

Yes, it probably would.

I just started having this issue and the machine has a static IP and always has had one.

Any other suggestions?

aware_support

This is definitely a problem of an IP address change or your Internet connection going down. If this happens Aware IM needs to be re-started.

Thanks

Can you also tell me if when this happens does it also break the connection with the database running on the same machine?

I'm also getting "Connection with the server could not be established" that I can't explain.

"Connection with the server could not be established" - you will need to restart Aware. This will re-establish your JDBC connections to the db

Good luck

I had this problem a while back. Don't know if it will help in your case, but mine was solved instantly by increasing the memory allocation for JBoss from default 96m to 128m in the /samples/startupOptions.props file. (Section 2.3.3 in Installation Guide).
In my case, I determined a cause was I had a lot of dynamic calculations which was apparently running over the memory allocation and crashing the system.
Hope this at least gives you a few more thoughts.
