Hi, I get the following error message every 10 seconds in my Solaris qmgr logs. This rotates my logs quite fast, which is really annoying. How can I find out which application is creating this error. If I knew the channel name it would be quite easy to find out because we use a Channeldefinition per application. Since the connection breaks so fast I am not able to find it out with a connection list, channel status list, etc.

Any Idea?

Code:

----- amqrmrsa.c : 459 --------------------------------------------------------
07/18/06 03:03:59 PM - Process(23537.1777) User(root) Program(amqrmppa)
AMQ9665: SSL connection closed by remote end of channel '????'.

EXPLANATION:
The SSL connection was closed by the remote end of the channel during the SSL
handshake. The channel is '????'; in some cases its name cannot be determined
and so is shown as '????'. The channel did not start.
ACTION:
Check the remote end of the channel for SSL-related errors. Fix them and
restart the channel.
----- amqccisa.c : 1305 -------------------------------------------------------
07/18/06 03:03:59 PM - Process(23537.1777) User(root) Program(amqrmppa)
AMQ9492: The TCP/IP responder program encountered an error.

EXPLANATION:
The responder program was started but detected an error.
ACTION:
Look at previous error messages in the error files to determine the error
encountered by the responder program.
----- amqrmrsa.c : 459 --------------------------------------------------------

Have you tried starting the qmgr with all channels closed and opening them one by one to find the culprit ?

You can get this channel name:
- if the codepages are different on the client and server side
- if the SSL authentication fails

I can not just stop the channels because it is the queue manager used by our application developers for tests. So I am not allowed to cut them of during the day.
@Tibor what can I do to achive this in order I can see the name?

Hi, I have now stopped and started again all the SVRCONN channel one by one. Every time I waited if the error disapears, but it didn't. I have no Idea who causes the problem. Any more Ideas?

You could switch on the tracing, but the amount of traces can drive you crazy... perhaps when you switch only the ssl trace

Even in the Trace of the affected amqrmppa process had a empty channel entry on that timestamp

And the SSL specific trace is not readable and can not be displayed with dspmqtrc.
