Physics going crazy on dedicated linux server

Hey guys,

my players reported that my server dont have any physic limits and therefor the force of the thrusters and wire_forcer for example are way higher as usual.
I tried to restrict it with the physenv.SetPerformanceSettings function in lua but I dont know the exact default values.

System running:
Linux Debian 7 @64Bit
Intel i7 4770K
Intel 530 SSDs

uname:
3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt11-1 (2015-05-24) x86_64 GNU/Linux

Is this a known bug?

#bump

Anyone? :cry:
