tor_assertion_failed on low memory
Tor crashed with the output below. This was seen on a VMware VPS, running on a fully-updated 64-bit CentOS v6.8 system with 1GB of RAM. No indication of low memory was seen in the system logs, and no swap space was apparently used by the system.
Sep 03 16:27:12.000 [notice] We're low on memory. Killing circuits with over-long queues. (This behavior is controlled by MaxMemInQueues.)
Sep 03 16:27:12.000 [notice] Removed 782124800 bytes by killing 3 circuits; 1120 circuits remain alive. Also killed 0 non-linked directory connections.
