Is it possible that one of your systems has run out of file descriptors? Because every socket is also a "file" in Unix and also occupies FDs. Just a wild guess anyway.

Have you checked the SSH log at the server side and does that give you any clues?

NAME
mosh-client - client-side helper for mosh SYNOPSIS
MOSH_KEY=KEY mosh-client IP PORT mosh-client -c DESCRIPTION
mosh-client is a helper program for the mosh(1) remote terminal application. mosh itself is a setup script that establishes an SSH connection, runs the server-side helper mosh-server, and collects the server's port number and session key. mosh then executes mosh-client with the server's IP address, port, and session key. mosh-client runs for the lifetime of the connection. The 22-byte base64 session key given by mosh-server is supplied in the MOSH_KEY environment variable. This represents a 128-bit AES key that protects the integrity and confidentiality of the session. For constructing new setup wrappers for remote execution facilities other than SSH, it may be necessary to invoke mosh-client directly. With the -c option, mosh-client instead prints the number of colors of the terminal given by the TERM environment variable. SEE ALSO
