Ok, this makes sense. Because we are now responding to these messages with a different thread all the available threads are being used up. How many BACnet data points do you have and why type of hardware are you running on?

We've made the thread pools adjustable in the next version of Mango 2.6 but here are some temporary replacement files to increate your threads:

m2m2-2.5.2-configurable-thread-pools.zip

This will increase your high priority threads from 100 to 1000.

1. Place the classes folder into overrides/classes, ensure you don’t overwrite anything that is already there

2. copy the properties about the configurable thread pools from the env.properties file included

— Mango needs to be shutdown at this point —

3. Remove ma-priv-1.2.4.jar and move the ma-priv-1.2.5.jar into lib

4. Start Mango back up and see if this problem is resolved.

There is a way to do this exactly the way you want but I'll share a few other ideas that you might be interested in.

I would suggest using the Date Bar. To enable this edit the menu item and select "Data and Rollup".

You can also make buttons to control the date bar like in this example https://help.infiniteautomation.com/buttons-to-set-date-bar/

You can also set a default rollup and chart type for each Data Point when editing the Data Point details on the Data Source page.

Here is an example of using the date and rollups from the date bar. If you set the default rollup for the Data Point then this will be passed through

    <ma-watch-list-chart watch-list="designer.watchList" points="designer.points" from="dateBar.from" to="dateBar.to" rollup-type="dateBar.rollupType" rollup-intervals="dateBar.rollupIntervals" rollup-interval-period="dateBar.rollupIntervalPeriod" simplify-tolerance="dateBar.simplifyTolerance"></ma-watch-list-chart>

Look in your /logs/ma.log file for errors. There might be something more specific there.
