That's a big outch: Be Careful what you Scan for!
Just to quote SANS:
After some fun and games at one customer site in particular, I found that the SSL services on the earlier versions of the HP Proiliant Servers iLo ports (iL01 and iLO2) are not susceptible to heartbleed.
However, their implementation of SSL is fragile enough that scanning them for the Heartbleed vulnerability will render them inoperable. This affects Proliants from G1 all the way up to G6, as well as many of the HP Bladesystems.
