Hi again Markus,
I've checked my own logs and found SSL handshake failures starting
on April 8th, or the day after Heartbleed was disclosed, as can be
seen below with the number of errors per day :

Interestingly, my version was neither upgraded nor restarted during this
period, so it cannot be caused by a code change, and is very likely caused
by bots trying the attack. So I think it's also possible that you're
experiencing the same things and that you didn't notice them before
upgrading and checking your logs.
Hoping this helps,
Willy
