Hi everybody
May be someone can help with this warning:
The security update (Tor v0.2.8.9 running on FreeBSD with Libevent 2.0.22-stable, OpenSSL LibreSSL 2.4.3 and Zlib 1.2.8.) shows the following log entry each hour:
Oct 19 02:51:07.000 [warn] Your system clock just jumped 136 seconds forward; assuming established circuits no longer work. Oct 19 02:51:07.000 [warn] assign_to_cpuworker failed. Ignoring. ...

The warning first appeared on 2.8.7 after update on September 13th (Tor v0.2.8.7 running on FreeBSD with Libevent 2.0.22-stable, OpenSSL LibreSSL 2.4.2 and Zlib 1.2.8.). That time I switched back (Tor v0.2.7.6 running on FreeBSD with Libevent 2.0.22-stable, OpenSSL LibreSSL 2.4.2 and Zlib 1.2.8.) and the warning disappeared.
What can I do?
The warning is reproted in tor-talk: https:// lists.torproject.org/pipermail/tor-talk/2016-October/042425.html
Thanks for reporting this issue - you could open a bug on our bug tracker under Core Tor/Tor: https://trac.torproject.org/projects/tor/newticket
It would help us to know if it's just FreeBSD, or just LibreSSL.
Maybe mention the bug number on tor-talk, so that poster can provide more details?

felix,
that might not be related to Tor, but to your host's clock setup and/or your jail's setup.

Good to see Tor in a jail runs for you. For me it did until 0.2.8. You want to take a look at https:// trac.torproject.org/projects/tor/ticket/20423 ?
