We fixed a bug like this in 0.2.9.6-rc.

It was caused by DNS resolves that received no reply and didn't timeout.
(DNS resolution occurs on the main thread.)

Here's the ChangeLog entry and bug:
https://gitweb.torproject.org/tor.git/tree/ChangeLog?id=1f6c8eda0073f464b7d23323251d72822f0a18bd#n262
https://trac.torproject.org/projects/tor/ticket/20423

You can help us diagnose this issue by providing the log lines just
before:

Using debug logs should help us identify the exact function call
causing the issue.
