Dear relay operators,
I recently upgraded one of my relays to Ubuntu 22.04 and now tor keeps crashing. I debugged a little bit and saw the following error in the log. It appears that it's due to seccomp not allowing "rseq" syscall, and possibly related to the latest version of Glibc.
I temporarily mitigated the issue by turning off sandbox mode (remove "Sandbox 1" in torrc). Does anyone know how to properly resolve the crashing issue?
Cheers, Danny Chen --
