Sudden 2013 Errors 'reading initial communication packet'
Today I'm suddenly experiencing the following error when a specific application attempts to connect to a database: ERROR 2013 (HY000): Lost connection to MySQL server at 'reading initial communication packet', system error: 0
There is another host running a near mirror-image of the app and isn't experiencing this error.
What are some things I should be looking for? I cannot recall any recent permissions modifications or changes in our network.
