dns resolver crash

[Amber Hu]

Hi Experts,

We are using gRPC 1.47.5 and found a crash in the daemon acting as gRPC client if there is network disrupt. From the stack, I could see it is the same issue as https://github.com/grpc/grpc/pull/29903. My question is when I try to reproduce it on another similar setup using same gRPC version by disconnecting the network, but could not get the daemon crash. I could not understand what difference in the setup might cause the different behavior, so I turn to seek help here.

Thanks for your time.

The behavior of that bug is not going to behave deterministically.  It depends on the exact timing of activity in multiple threads, so I don't think it's something you'll be able to consistently reproduce.

I suggest that you upgrade to a more recent version of gRPC.
