Segfault in falco

[jacques-]

Falco binary seems to segfault every 10 - 30 minutes. No idea what is triggering this.

It's likely the same problem as #215. Could you try downgrading the sysdig version by hand and see if that fixes the problem?

I'm working on a fix for this (having falco use it's own standalone driver) right now.

Yup, downgrade worked, thanks!
