      Description

      This exception was observed on the mini cluster during query. It persisted across the reboot of 192.168.1.17 and the restart of all services. It was eventually cured by turning off all machines overnight and then restarting them (the hypothesis being that there was something overheating on the minis, which are after all pretty light weight devices). It is also possible that the problem was one or more services which were not terminated. All in all, this was a very odd exception. I could find nearly nothing about the underlying stack trace on the Internet. This ticket is just to make a record of the problem in case something like it ever reoccurs.

      ...1f1aa66b-8db9-4bad-b053-18c4235b7f1d,TcpEndpoint[192.168.1.17:52745]]; nested exception is:
