 I noticed an extreme increase of memory usage (increase by ~500MB compared
 to normal), after looking into the logs I stumbled upon:

 {{{
 circuit_mark_for_close_(): Bug: Duplicate call to circuit_mark_for_close
 at ../src/or/onion.c:182 (first at ../src/or/command.c:559) (on Tor
 0.2.8.6 )
 }}}
 (6 times within one second)

 also in the logs 10 seconds before the log entries above:
 {{{
 Removed 109202016 bytes by killing 2 circuits; 5252 circuits remain alive.
 Also killed 0 non-linked directory connections.
 }}}
