#748: Exception when adding change
-------------------+--------------------------------------------------------
Reporter:  catlee  |       Owner:

-------------------+--------------------------------------------------------
 I hit this exception when a new change was detected via our hg poller.
 The change was eventually detected again, and inserted properly.  IIRC,
 mysql connections need to be recycled every so often, depending on server
 configuration.  (wait_timeout on this server is configured to 600 seconds)

 See docs here under the 'pool_recycle' parameter:
