Hello Champs,

This message is info only and can be safely ignored. Alternatively, you can turn it off by setting the TcpInputProc log level to WARN.

If you can't restart splunkd yet, simply run:
$SPLUNK_HOME/bin/splunk set log-level TcpInputProc -level WARN

To make the change persistent:
* Create or edit $SPLUNK_HOME/etc/log-local.cfg

* Add:
category.TcpInputProc=WARN

* Followed by splunkd restart.

Running version 9.3, the log-local.cfg doesn't seem to be applied.
Even after a restart, Splunk is throwing >10 of these INFO lines per second.

This message should probably be moved to the DEBUG category... 

 

Spoiler
It is possible there's another issue with my instances, but this mess of logs is making it very hard to troubleshoot.
`splunk set log-level TcpInputProc -level WARN`  does work
Modifying log.cfg also works

Following this thread as well, as I have observed the same issue following an upgrade from 9.1.2 to 9.2.1

Still an issue in 9.3.2

 

The concept of "ignore all INFO level" messages doesn't sit with me well as a solution, there are useful messages at that level.

Same with 9.1.4.
