    Description

      For some performance tests, the python sdk twisted api is used. When upgrading the twisted api to 3.0.0 python sdk in perfrunner, I am seeing lots of timeouts from LCB. If you scroll down you can see the errors: http://perf.jenkins.couchbase.com/job/ares-tmp/42/console

      It seems only twisted api tests see this issue and im not sure if its LCB or python sdk problem.

      In several cases these errors happen immediately and some they happen after about 5 minutes.
