Bug Description

I'd never seen this before. ATOP was dying before even getting started, according to GDB. Six hours later, it works fine.
At the time, I had some very memory- and disk-intensive processes running, moving 20GB files around.

Having this on 15.04, atop is running as a daemon to collect information, but crashes from time to time.

As atop has no systemd script but is started using sysinit unfortunately.
That is a pity as systemd could nicely respawn it when this happens with minimizing the impact...

One thing I'd like to mention. I login as soon as Ubuntu will allow it. The login screen pops up and then goes away briefly. During that going-away time, I go ahead an enter my login credentials, and I'm usually logged in by the time the start up sound drums. As a matter of fact, the drum-sound is slightly cropped off at the end because I'm logged in before is completely sound (I think).
