QMC tasks got stuck and shows running until we abort and re-run it.

Can someone tell what can be the cause for this? Is there a solution for this? 
Also, it got stuck meaning task failed but status shows running indefinitely.

1- Go to default location of the config file:  C:\Program Files\QlikView\Management Service\QVManagementService.exe.config 
2-  Then adjust the QMSChunkSize from 100 to 20

• <add key="QMSChunkSize" value="20"/> . The value 20 is not a set value. It may be necessary to test different values, such as 20,15,10, 5, etc, dependent on the system and environment. 

3- Restart the QDS service.
4- Restart the QMS service.
