Conflict between editing labels and polling /users

Not sure if this is a related issue.
Today I tried to edit a DX tag on my remote KiWi and got a red splash screen message that I hadn't seen before, stating "Must close all admin connections before attempting this operation."
This turned out to be due to the site admin regularly connecting to my KiWi from a local IP in order to poll and gather /users information.
I'm perfectly happy with this, but it does stop me from being able to remotely edit or add any DX tags.
Is this a new feature or something else ?

Code was added to help prevent the label and configuration files being corrupted (or losing changes) due to the "multiple writer" problem. Changes from a user connection that require admin privileges (label edit, freq cal, freq offset, IQ cal) now require that there be no open admin connections that might cause conflicting writes.
/users
access obviously never does any writes, and so I shouldn't be excluding that. Will fix..Okay, I was a little confused by this until I did some testing. Polling /users (i.e.
curl my_kiwi:8073/users
), or /status for that matter, will not cause this problem. Only the presence of an open admin connection at the time editing labels from a user connection is attempted.Do you really have a polling function that makes repeated /admin connections? If so, does it only look at the status tab?
Hi John,
I didn't implement the /users polling, so I don't know how it is being used.
I'll try and find out from the site admin and report back.
Thanks for looking at this.

Was there ever any more info about the exact failure mode here?
Hi John,
We didn't prove it 100%, but it is likely that an admin connection had been inadvertently left open by the site admin.
There are 8 Kiwi's on the same site, plus a lot of other remotely operated kit, so it's quite easy to become confused about what you were connected to and why.

I have 4, sometimes 5 at my location running. I brought some order to things by assigning the LAN IP and port as such:
192.168.1.73:8073 ..... 192.168.1.75:8075 etc.
Hi Jim,
I think that is how it is already organised, but it's not my site or network, and there is a LOT of radio kit and automation in operation.
I'm just a lucky tenant who gets to share the infrastructure :-)
