EPIPE - Unexpected error condition 32/Linux, please report this as a bug

[davmillar]

Received the error "Unexpected error condition 32/Linux, please report this as a bug" in our logs. The error code comes back to EPIPE.

I'm not familiar enough with error codes to understand the impact to the module.

1. Should the __try_read_sock sub return 0 in this case, or retry like it does with EINTR?
2. Is there further error handling required outside of the __try_read_sock sub when this happens?
3. How would I go about debugging why the pipe was broken -- is there something in the host OS that would log info about this, or should I inspect the Redis server logs and network traffic?
