    Description

      I enabled unit tests for our watson builds – first enabled it only on centos7 and want to see how it goes.

      The unit tests are sometimes hanging. I did multiple runs of this on various platforms (linux) and they are more or less working most of the time. But during my tests I saw it hanging once in a while. It didn't hang for the last 2-3 days, and I enabled it on our regular builds. Lo and behold the very first run, it hangs.

      I killed the test and the build proceeded after that. The link to the build is here: http://server.jenkins.couchbase.com/job/watson-unix/1119/

      I don't know what information (logs etc) I can provide for you to debug this. If someone can guide me what I should collect, I can do that the next it happens. I also don't know exactly which test is hanging. The processes that were running at the time of the hang were:
