It sounds like your Tor process is mysteriously disappearing.

You might like

My guess is that it's running out of memory, and the system is
quietly killing it. In that case 'dmesg' would give you some hints
to confirm it.

If that is the case, it's likely happening because all of these Tor
clients are creating many more TLS connections, and each of those TLS
connections makes OpenSSL use more memory. The current best fix is
'then give it more memory'.
