[Flightgear-devel] FG-OSG: periodic hangs at KSFO

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 With the CVS-HEAD version of FG I'm experiencing periodic hangs if I start at KSFO. The sim runs at about 40fps for a second, than just hangs several seconds, then it runs again. Tried to wait a few minutes to see if the hangs would disappear with time, but it does not change anything. I've been experiencing this problem since the swith to OSG and it did not change with today's version (using OSG CVS now). Appart from that everything works very well. If I start at a location which I do not have scenery for it works without any hangs and with hardly any loss of frame rate compared to the plib version (if any). During the hangs FG put's out hundreds of these warnings: Warning:: Picked up error in TriangleIntersect (2.19353 -4.90415 -1.87296, 2.11905 -4.9177 -1.96142, 2.1952 - -4.73948 -1.89497) (nan, nan, nan) Warning:: Picked up error in TriangleIntersect (2.11905 -4.9177 -1.96142, 2.11905 -4.73485 -1.97124, 2.1952 - -4.73948 -1.89497) (nan, nan, nan) Warning:: Picked up error in TriangleIntersect (2.1952 -4.73948 -1.89497, 2.45243 -4.73948 -1.90708, 2.19353 - -4.90415 -1.87296) (nan, nan, nan) The backtrace during the hang looks like this: (gdb) thread apply all bt Thread 3 (Thread -1338328160 (LWP 13441)): #0 0xffffe410 in __kernel_vsyscall () #1 0xb75312e9 in ioctl () from /lib/libc.so.6 #2 0xb6b32b20 in snd_pcm_hw_writei (pcm=0xafefdd0, buffer=0xaff2070, size=1024) at pcm_hw.c:745 #3 0xb6b2324c in snd_pcm_writei (pcm=0x400c4150, buffer=0xaff2070, size=1024) at pcm_local.h:401 #4 0xb76e116f in alsa_blitbuffer () from /usr/lib/libopenal.so.0 #5 0x0d6ab510 in ??
