This usually means one of:

* MySQL server process crashed or was killed/restarted while you were

* MySQL connection was dropped due to too-large data being transferred,
larger than the maximum packet size setting (this is unlikely here)

* A database administrator killed your MySQL connection manually while
working with it

A timeout closing your connection during the 'deleting old messages'
phase is entirely possible, especially considering that you're on shared

This should be relatively harmless, that's not a critical point in the
upgrade, so the next run should have ensured you were in a consistent state.
