Issue/Introduction

What condition occurred that caused the TIML to write these messages: 

 2022-xx-xxxx:xx:xx..TISRVMSL TIML TASK=00000074 xx/xx/2022 xx:xx:xx SOCKET RECEIVE PROBLEM. NOTIFY CLIENT, CLOSE SOCKET
 2022-xx-xxxx:xx:xx..TISRVMSL TIML TASK=00000074 xx/xx/2022 xx:xx:xx SOCKET ERROR, RETCODE=-0000001, ERRNO=00000054

 Question: 
  - What exception(s) has the TIML encountered to write these messages.
  - Where to  look for information on how to "NOTIFY CLIENT" -or- was the client notified prior to this message being written?

Environment

Release : 8.6

Component : GEN TCP/IP DIRECT CONNECT OPTION FOR CICS

Resolution

- What exception(s) has the TIML encountered to write these messages.
The ERRNO=00000054 means that the connection to the destination host is not available.  A return code 54 is a Connection Reset by Peer.

- Where to  look for information on how to "NOTIFY CLIENT" -or- was the client notified prior to this message being written?
In this case the SOCKET RECEIVE call got a return code of 54.  Since the Socket connection is not established, the TISRVMSL, it cannot send a response back to the client.  So the client does not get a message.  The client does get a 10054 and retry logic may be added within the function CI_TCP_DPC_handleComm_Complete in the Gen user exit CITCPCLX.C on the client side.
