The message is informational.  There is probably nothing wrong with
the application, at least if the message occurs only rarely (at an
interval less than 4 messages every 10 seconds or so).  If the message
occurs all the time, then there could be a performance problem with
the application.

You should be able to turn of the message with "prctl --fpemul=silent".
