A Linked monitor will not trigger an upstream monitor after zone changes

[lk777]

I am experiencing the following issue with the linked monitors.
My setup:
A High Resolution monitor (Nodect): Linked Monitor - Low Resolution (Modect) *(Storage JPEGS, Video writer - disabled).
Everything works until I change/add zones on the Low Resolution monitor. It will not trigger a High Resolution monitor any longer after these changes.
And only zoneminder service restart fixes it.

What version of ZM? I fixed an issue like this back during 1.35 development, but am fairly confident in the code now.

Ubuntu 20.04 LXD container (a host 20.04 as well)

ZM 1.36.4

And one more.
Just do not want to start a new topic:
Ubuntu
/usr/share/zoneminder/www/api
not all files have the right ownership, at least, in my installation they were root:root instead of www-data:www-data

It flooded logs with the cake permissions errors.

Update:

Now it is v1.36.5
It is not only changing zones (as I initially thought) but even opening/closing zones breaks monitors link.

same issue here. linked monitors work fine until you change the motion zone in the lower res monitor... v1.36.5

It has been mentioned on a few threads. Either a ZM restart or a change of the monitor type (then change back) will sort it.

thanks Magic, that's reasonable. I'll give that a shot. Still a little new to ZM
