Occasional segfault when starting

PherricOxide commented 11 years ago

There seems to be an occasional (it doesn't happen every time) segfault when loading.

Might be related to #1?

Thx for this one. It's an old bug that I thought was fixed long time ago...

I am right now rewritting most of that code to both finally create a decent implementation for that functionality and support more than 1800 services (right now there is 8k) :)

This is somehow OS dependent. I will investigate it more throuroughly.
