Dear Sedo, you get this error in a Java application which is issuing Broker calls. Basically, the problem is that the Broker cannot process the request issued by the Java application in the TCP/IP communicator. There are 2 ways to get more information: you might check the output of the TCP/IP communicator task for error messages. Or you can run the Java application with trace enabled, use -Dentirex.trace=3 in this case and post the output here or send it to support. Usually this error is due to resource shortages (especially NUM-COMBUF and NUM-WQE). Kind regards, Rolf ---

we have increased NUM-COMBUF Parameter. Now we are testing the environment. It seems to work 😉 ---

Increasing of value \<\< NUM-COMBUF \>\> from 100 to 150 helped to solve this problem. Thank you ! ciao Sedo ---
