Rendering crashes intermittently (about 50% of times) on Sun V20z (dual AMD opteron) with 2.6.15-1.1830_FC4smp. The same Cinelerra RPM version 1.2.2 and kernel combination works fine everytime on Pentium 4 HP workstation. I also tried using LD_ASSUME_KERNEL=2.4.19 but still geting killed, though less frequently.
Any leads on this please ??

Thanks,
Umesh

Here is the long crash output (sorry for the long size, but I wanted to give complete output) -
