Monitor: Stop running nchan processes log is repeating but client is silent

[MrChip]

I recently upgraded to 6.12, and I'm now at 6.12.6 on 3 servers. I'm seeing these log messages repeating over and over on 2 of the servers.

Jan  4 13:56:08 bailey-un monitor: Stop running nchan processes

 

The TLDR version:  I see the nchan log messages repeating over and over on one server after the client PC goes to sleep and the browser there stops accessing the web GUI without logging out. This has happened on a second server but I can't confirm at this time whether it happened again today. I'll have to confirm that later when the server is accessible again. Today, it did not occur on a third server - just one message there.

 

In detail:

On the server shown here, the message repeats every 33 seconds.

I've seen an earlier thread (https://forums.unraid.net/topic/144710-since-6124-monitor-stop-running-nchan-processes) but it didn't seem to come to a resolution for what I'm experiencing.

 

These messages start after the client PC is put to sleep. I didn't close the browser tab or log out of the session - I just put the PC to sleep. There should be no further activity from the browser session on that PC until it wakes up again. But these messages keep being generated over and over.

 

The messages stopped when a new GUI session to the server was opened from a different client PC on a different local subnet.

(This is the end of the log and was copied at 21:06 local time, so there's nothing in the log after 20:36:58.)

 

One of my servers didn't get into this state today. I recorded a single instance of the log message when the client PC (same client PC as above) went to sleep.

My third server has shown the repeating nchan log messages in recent days, but it is currently in accessible and likely down. (I'm not there to investigate it further right now so I can't say if it started these messages today or not. The same client PC was connected there too.)

 

I think that the repeating messages are a bug - a single message makes sense when the client PC goes to sleep, but repeating messages don't make sense as the client is now silent.

 

Your thoughts?
