On what hardware/OS this relay is running? It seems to be due to hitting
resource limits. { src/or/onion.c:238 + "assign_to_cpuworker failed" error }
Though neither circuit_mark_for_close() should be called twice nor tor
process should crash.
Do you see other warnings? Messages about the reason of tor termination?

btw, there is a ticket for this very issue:
https://trac.torproject.org/projects/tor/ticket/20059
As long as it happens at the same lines of code I guess all this has
common reason. "assign_to_cpuworker" error is a kinda consequence of
hitting rate-limits (likely RAM usage).

Probably there is a memory leakage somewhere that makes everything fail
and get process eventually killed by OS.
