Problem:

RECU abend is issued when executing COBOL programs recursively under CICS. There is a fix which changed ES MTO behavior but no explanation in the release notes.

Resolution:

This can be remedied by setting the ES environment variable ES_PLI_SUPPORT=Y. This should prevent the RECU abend if the program is a COBOL program.
