Error description
In a scenario where OMPROUTE encounters a receive error on the informational sockets connection (internal loopback) between OMPROUTE and TCPIP stack, TCPIP resets the connection and OMPROUTE terminates abnormally. For example, the following messages are issued leading to OMPROUTE termination: EZZ7842I INFORMATIONAL RECV() ERROR, ERRNO=1121:EDC8121I CONNECTION RESET., ERRNO2 76650446 EZZ8074I OMPROUTE PROCESSING ERROR EZZ7805I OMPROUTE EXITING ABNORMALLY - RC(1) Even with error2 76650446 (JRSOCKETCONNDROPPED) and that the TCPIP stack is still active, OMPROUTE will not try to open a new connection for recovery. In this case, OMPROUTE has to be manually restarted.
Local fix
Use automation utility to monitor for EZZ7842I and ERRNO2 76650446 to restart OMPROUTE. For other errors indicating TCPIP stack outage (for example, 746D0381 JRPREVSOCKERROR or xxxx0296 JRTCPNOTACTIVE), restart TCPIP and OMPROUTE.

The informational socket connection is aborted for an unknown reason and OMPROUTE treats this as a terminating condition. One possible reason for the connection aborting is a NETSTAT DROP was issued against the connection. OMPROUTE should treat this as a retry condition and attempt to create a new informational socket connection. If the new informational socket cannot be created then OMPROUTE should terminate. +-------------------------------------------------------------+ + Please check our Communications Server for OS/390 homepages + + for common networking tips and fixes.
