Oh I didn't think about going that lowlevel :) Could you run ldd on gmond also?

Rechecking this with strace log shows that it looks like double loading of those modules? http://pastebin.com/BjdCGgbj > On Sun, Feb 09, 2014 at 03:28:10PM -0500, Jeff Layton wrote: > On 02/09/2014 02:48 PM, Jeff Layton wrote: > >On 02/09/2014 02:28 PM, Maciej Lasyk wrote: > > > >>You could also try to catch on which particular check this segfault > >>happens..? > >Not sure how to check this.
