But after 4 days or so a restart of the service "tor" fails with messages like : Sep 14 11:27:10.000 [warn] Could not open "/var/lib/tor/data/keys/secret_id_key": Required key not available Sep 14 11:27:10.000 [warn] Error reading private key from "/var/lib/tor/data/keys/secret_id_key" Sep 14 11:27:10.000 [err] Error loading private key. Sep 14 11:27:10.000 [err] Error initializing keys; exiting Sep 14 11:27:10.000 [warn] Couldn't open "/var/lib/tor/data/state.tmp" (/var/lib/tor/data/state) for writing: Required key not available Sep 14 11:27:10.000 [warn] Unable to write state to file "/var/lib/tor/data/state"; will try again later No way to get it repaired other than rebooting the machine.
