Comment (by iwakeh): Further investigation lead to a thread dump with 200 waiting backend queries, but no such query thread. Logs didn't reveal anything suspicious except very few errors due to weird data input (reproducible by entering an ipv6 address with additional percent sign number combination). In addition, ExoneraTor often is queried more than 3 times per second, which is surprising, but not at all a performance problem. Thus, a temporary measure can be to simply catch all possible errors and then proceed when we catch something. Please find a minimal catch-all patch [https://gitweb.torproject.org/user/iwakeh/exonerator.git/commit/?h=task-24534 -debug- patch&id=a8bb4babdb0a55e5f78b9d226c59145c16f06bff&context=3&ignorews=1&dt=0 here] (all changes other than adding try-catch were made to avoid checkstyle complaints). -- Ticket URL: <https://trac.torproject.org/projects/tor/ticket/24534#comment:2> Tor Bug Tracker & Wiki <https://trac.torproject.org/> The Tor Project: anonymity online
