Never change anything on Friday at 5pm.

SEVERE: Socket accept failed SSL handshake error No available certificate or key corresponds to the
SSL cipher suites which are
        at Source)

This is the reason you never change anything on Friday at 5pm. While attempting to update the SSL certificate for the MySQL Enterprise Monitor (for which the process has no documentation), I managed to break it in a way that caused a few hundred megs of these errors to dump to the catalina log for MEM. Oh, and it meant no monitoring was taking place for a few minutes.


Lesson re-learned. Glad I made a backup of the keystore before I started mucking with it. Now we wait for MySQL to provide me with the correct documentation (after they write it some time this weekend). You would think someone would have already encountered this with their product considering how long it’s been out there already.

At least we have monitoring back.
