Non-Graceful Disconnect causing issues with UD Mobile (connection error) and ISY Admin (already subscribed)

[macjeff]

I was told there was another post about this but cant find it.  If there is I will close this and move over.

on ISY on Polisy

In ISY ADMIN, I randomly got ALREADY SUBSCRIBED for a while.

Since updating with the latest Polisy update those continued but now the same type of errors with UD Mobile.

A reboot of the ISY always clears this or you can wait it out (hours)

I put in a ticket and was told that others have found the issue was ST Inventory.  They said its not gracefully disconnecting sometimes when it connects.

(If you want more info see the ISSUE on GitHub - https://github.com/UniversalDevicesInc/UD-Mobile-iOS/issues/65)

So I turned off ST Inventory on Friday with no issues all weekend.

I just turned it back on (Monday) and within a couple minutes I get errors.  I can easily reproduce (more than random) with UD Mobile on iOS.  Just force quit the app and run it and you will see an error.  If you repeat the steps a couple times it eventually gets in.  Turn of ST Inventory and the errors go away.

Errors seem to be only on local network but thats because outside the network I connect using ISY portal which maintains a connection.

I did try the 1 hour short and 1 Day poll for ST Inventory but that did not help.  Within a minute of turning the Node server on the errors come back.

For now leaving it off as I only use that once and a while and when I do need it I can turn it on, get my data, and then turn it back off.  its not used in any programs.

To clarify,  this issue appears similar to issues experienced with PyISY when subscription sockets were not being closed gracefully.  Not sure if it is related.

I am 100% sure its ST Inventory.  Turned it off since yesterday and not one issue.  Turned it back on just now and errors came back.

ran the latest update and immediately got this error back again.  It seems to be when I update from test flight manually.  Usually I have auto updates.
