IMS Stub (IMS - QNX)

Hi We have an IMS stub working as a server between IMS and QNX. Since last week the server (bobol ims) generated 1.6 m lines with the errors : 0002 0200 and 0003 0003. my question is which is leaving the conversation open or where can I detect the cause of the error?. Thanks in advance.-

If this is reproducable a Broker trace (level 1) will provide more information.
You should also check your timeout settings in the Broker attribute file, maybe they are too low. And there might an application issue that the program does not react in a proper way when one of these errors occur.

Kind regards,
