We are on PI7.3 SP11 dual stack system, suddenly we have started observing "MAPPING"> JCO_SYSTEM_FAILURE java.lang.reflect.UndeclaredThrowableException error in one of the PI environment. This is problem observed across multiple synchronous scenarios. Also this is intermittent problem where all the messages are not failing but few are getting successfully processed as well.
Please note we have already done below checks/actions
looking at error it seems the issue lies when JCO tries to communicate with java and ABAP stack during mapping runtime, however by seeing all messages are not failing, it might have to do with system performance tuning?
Additionally got below error logs from dev_jrfc.trc file from j2ee/cluster/server* location but not able to figured out the error, Appreciate any help here
