text: Title: Lost connection to MySQL server during query
  Body: When my application throws an exception and I try to access an endpoint again, it returns the error "**(2013, 'Lost connection to MySQL server during query ([Errno 104] Connection reset by peer)')"**.
  
  It is as if it were not connected to the database or as if it did not refresh. Using SQLAlchemist I edited the parameters "**pool_timeout=60, pool_recycle=280, pool_size=20, max_overflow=50**" when I call create_engine, but in ORMAR I don't know how to do it.
  
  Any idea how to do it?
  
  Thanks!
