Possible memory leak error message

WebThings
#1

I’m getting around 20 instances of this error message a day.
Is it worth investigating?
If so, what further information is needed?

It’s not really a memory leak. It’s a side effect of opening a separate WebSocket per thing. That has actually been resolved for the upcoming 0.10 release, so this message should go away.

I too see this error quite often. When is the projected release date for 0.10?

Should be within the next month.

Just got this too (on 0.12.0)

Also the reason I even noticed it in the logs was none of my zigbee devices were responding at the time (reboot solved it).

This message now occurs quite rarely and is described as a non-issue, see Screeching to a halt
