Parser error when 'Check all is answered' is run [bug] [EMC]

[avanoostrum]

In the EMC test installation on the test server clicking check all is answered for all sources generates the following error:

Communication error
parsererror
00000{"current":"3.82","max":100,"percent":3.82,"timeTaken":1369,"timeRemaining":34469,"text":"Checked 1740 tokens.","finished":false}

Project version	1.9.1p7
EMC version	1.8.7
EMC build	20190909
Gems version	1.9.1p7

The error is only shown in test, not in production. This leads to incomplete updates of assigned tracks without any notice. Workaround: running the recalculation again and again until no further updates are reported.

Due to sometimes very complicated track logic this might be unavoidable, but at least it should be reported that recalculation was incomplete and needs to be rerun until no further changes are reported.

Is this a problem for every installation? My test installation can not even start this process as there are to many answers.

[roelfaber]

The problem is actually that this process fails without a notice or log entry when in production mode. No way to detect if the process has finished or not. It happens regularly in current more complex production projects.
The status finished: false should generate a flag or button to restart this calculation until the status finished: true is reached.
