We updated the SAP kernel on our test BW system on April 21st
2014.
Since then we are seeing errors/warnings in SM21 log. The errors are
only for the application server.
**************************
Communication error, CPIC return code 020, SAP return code 223
> Conversation ID: 63953543
> CPI-C function: CMSEND(SAP)
**************************
At this point I am sure that this is something related to gateway but
notable to say why this is happening.
1) We are migrating to new kernel on production next week. I want to
make sure that this will not cause any issues on the production. For
that I need to find out exactly what could be causing this.
2) I would like eliminate this error from the system as its annoying
to these errors continuously.
Your help is really appreciated.
Below is more details from gateway trace.
