We just ran into this issue and managed to find a solution that worked for us. It seems that Flyway uses at least two connections: one to lock the schema_version table, and one to actually run the alters. This issue occurs when the alters take long enough to cause the connection locking the schema_version table to timeout. The easiest way to fix this is the bump up the MySQL wait_timeout to something relatively large. In our case we set it to 480 minutes (or 28800 seconds):

set global wait_timeout=28800;
