Issue/Introduction

logmon probe will not start, and eventually goes red/reports max restarts.

Log shows the following over and over (the port may differ):

 

Mar  9 18:20:27:721 [139898666776352] logmon: sockServer: next available port is 48012
Mar  9 18:20:27:721 [139898666776352] logmon: sockServer: bind failed 98
Mar  9 18:20:27:721 [139898666776352] logmon: nimSession - failed to create server session on port 0, error code 98
Mar  9 18:20:27:721 [139898666776352] logmon: nimSession failed

Cause

caused by some conflict on the given port at the OS level

Environment

Release : 20.3

Component : UIM LOGMON

Resolution

resolution:

edit "controller" raw configure  (robot.cfg)

<controller> section

set:

first_probe_port = 480xx

where 480xx is one higher than the port reported in the error message.

So if the error says "unable to bind to port 48012", set first_probe_port = 48013
