Sudden Error in my test instance

I have done so many customization in my Sales Order a long back.
But today suddenly my test instance has got crashed.

I am receiving below error:

Does anybody have an idea about this?

Seems redis is down. Do bench restart.

Did you get any solution over this?

I am also facing the same issue and i tried restarting bench, update, redis update but still the same issue.

Please refer to this Error while bench update --reset
