Hello all,
we are experiencing random crashes in the OSG applications we are
developing under
Linux (realtime image generation with large area PagedLOD databases).
After several debugging sessions, I think I have been able to isolate the
problem further.
These factors do not seem to influence the problem:
OSG application - crashes happen also with the standard osgviewer
OS version - tested under Fedora Core 3 / 4
OSG version - both OSG 1.2 and OSG 2.0 have the same problem
PagedLOD database - tried with several databases, created with osgdem or
with
custom built applications,
or even in TXP format
Nvidia driver version - tried Linux versions 8174 and 9755
The problem instead seems related to the Nvidia control panel: I am able to
always trigger
the crashes by launching the Nvidia control panel (nvidia-settings) and
forcing Antialiasing
and Anisotropic filtering on. After that, If I close the control panel and
launch any osg application
with paging, after a very short time the app segfaults. From that moment
on, no matter what
are the settings in the Nvidia control panel, every app crashes regularly,
after a varying (short)
amount of time.
Following are some examples of debugger traces (osgviewer pagedDB.ive)
after the crash.
Note that the memory usage for the application is very low (7-8% at the
moment of crash).
Do you have any clue to where could be the problem?
Thank you
Andrea Damiano
