other RTC Codes and action to solve:
2F REQUEST HAS EXPIRED (TIMED OUT)
1D REQUEST UNSUCCESSFUL (out of IUCV path)
1E PATH HAS BEEN SEVERED
IUCV PATH's empty or IUCV Connection to DYNAMCMS Server was broken (perhaps of IPL VSE).
recomendation: increase OPTION MAXCONN in the CP DIRECTORY for VSE
restart DYNAMCMS to recreate the IUCV interface.
