Dgrpah alpha is getting crash after deleting predicate node

Hi,

yes my bad, I am using the 20.07.0 version.

I have already done the above 2 steps that you mentioned but in a few min, less than 15 mins alpha again crashed, as it stuck in a loop.

here are more logs, might help.

I didn’t understand the 3rd point,do I need to upgrade my dgrpah version, like this is bug existing in this version (20.07.0).

For the system configuration (as mentioned earlier), do I need to change anything in that?
