Is this issue fixed in 3.2.1? I noted this:
25838 prevent crashes due to timeouts when calling into the limiter
If not, is there a way to track the progress on the issue or a timeline
you could provide?

Server here means gen_server, an Erlang process behavior (think of it as a
class named *Server, if it helps). It should not bring down the node.

This is a server issue. From time to time one process does not respond to
another process in < 5 seconds and the caller crashes without a timeout.
Presumably this is because of short hardware resources.
There is no client-side work around I'm afraid.
