APAR status
Closed as program error.
Error description
In MQ NonStop 5.3, KeepAlive timeout (ETIMEDOUT) is detected and RCVR channel is INACTIVE. At that time, it is not listed as ESTB in SCF LISTOPENS. In MQ NonStop 8.1, MCA does not process the ETIMEDOUT and does not close the socket, leaving it listed as ESTB. TCP keepalive is ignored by channel connection. Channel is not disconnected when the connection is lost.
Local fix
Reduce hartbeat time below keepalive time.
Problem summary
Heartbeat timeout is evaluated but keepalive timeout is ignored.
Problem conclusion
The product has been changed to factor in keepalive timeout.
Temporary fix
Reduce hartbeat time below keepalive time
