Troubleshooting network communications
If you are experiencing problems with connections unexpectedly terminating, consider adjusting either the liveness or the idle timeout values.
For more information about liveness timeout values, see LivenessTimeout connection parameter [LTO], and the -tl server option.
For more information about connection timeouts, see the Idle connection parameter [IDLE], and the -ti server option.
