Currently (Late June 2016) the test format stress tasks are hanging and not failing as expected.
When running with format we expect that the test will finish due to one of two conditions:
- The format task completes its number of ops (normally 20000)
- The format task runs for more than its allotted time (normally 20 mins)
Hangs traditionally result when we have run with a small cache, due to worker threads running indefinitely when we have a full cache. However, if we have been unable to progress with eviction, we should see the ETIMEOUT error after 5 minutes.
The question is, why do we not see either of these events happening.
