Issue/Introduction

What changes can I make to resolve Gen 8.6 Multi Sockets CICS Listener TISRVMSL error messages:
TISRVMSL TIML TASK=######## MM/DD/YYYY HH:MM:SS DID NOT RECEIVE FULL CFB HEADER; SOCKET CLOSED

Resolution

The message "DID NOT RECEIVE FULL CFB HEADER; SOCKET CLOSED" is produced when the listener receives the buffer (the header part of CFBDATA) from TCP/IP and does not get the entire number of bytes of data.  It could be that the network data transmission is slow and the listener gave up before all of the bytes arrive or the packets get lost.  All that the Listener knows is it did not get the complete number of bytes after it tried a number of times and so produced the message and closed the socket.

Possible changes to address this are increasing the REATIME on the EZACONFG entry for the listener or setting the values in the TIRSLTMX parms REATOUTS and REATOUTM.
