Backtrace for the thread that has asserted:
I am hopeful the backtrace will be sufficient. There are a lot of sockets at work in a very complex system, so reducing it to a simple case is unlikely.
The assertion raises in my program when it is 1) under load, and 2) I hit ctrl-C or send a INT or TERM signal to end the program.
This is against commit ac40680ea2f6b32a3c of master.
