Issue description
The Jenkins build is showing intermittent failures for some of our automated tests on multiserver topologies. I'm not sure yet what the problem is exactly, but it seems to occur frequently enough (1 time out of 5) to warrant a dedicated bug report. The failures I've been seeing recently, and for which a set of logs is attached to this defect:
