Same problem

Totktonada commented 3 years ago

Looks like a problem around navigation within the msgpack stream. However I don't see an obvious problem in the code. How can I reproduce the issue?

I found the problem, I used one instance of the Connection in different threads, I create separate instances in each thread and the problem was solved :) @vadim-shadrin I hope this help you)

@memclutter Thanks for spotting the problem!

The README warns about this:

This driver is synchronous, so connection mustn't be shared between threads/processes.

Closing as invalid so.
