Interesting! Never saw that one before. Are there any clues before it in the log?

A stack trace would also help, if you can reproduce this with core dumping enabled.

Replying to nickm:

No, just the usual heartbeat stats. I changed the log level to 'info'.
I'll let it run for a week and see if it triggers again.

Is this about changing coredumpsize-max in login.conf?

It died again today, but this time without any apparently relevant log entry. Log entries are almost exclusively [info] level.

I'll come back once I can tell you more than that.

Finally admitting that 0.3.??? was a euphemism for Tor: unspecified all along.
