With yesterday's git for fgfs and simgear, after about 1.25 hours, fgfs froze and I had to use System Monitor to end process fgfs.
All seemed normal up to the freeze. OS, up-to-date FC14 on an I7 desktop with nvidia GeForce GTX 260, NVIDIA driver Version: 260.19.29. Command line (from fgrun wizard): /usr/local/bin/fgfs --fg-root=/home/dad/source-osg/fgdata --fg-scenery=/home/dad/source-osg/fgdata/Scenery:/home/dad/source-osg/TerraSync --airport=KLWB --aircraft=pa24-250-CIIB --control=joystick --disable-random-objects --enable-ai-models --enable-real-weather-fetch --prop:/sim/frame-rate-throttle-hz=30 --prop:/sim/menubar/autovisibility/enabled=1 --geometry=1680x1050 --visibility-miles=30 --bpp=32 --fov=65 --texture-filtering=16 --atlas=socket,out,5,localhost,5505,udp --atlas=socket,out,5,localhost,5500,udp --prop:/sim/rendering/shader-effects=true --nav1=109.5 --nav2=114.2 --adf=400 --dme=nav1 I had just passed Casanova VOR (116.3 CSN) on the 72 deg radial (approx. 7 nm out bound).
