threads parallelization

Hey there.

I've been using the threads package to parallelize some code. It's going well for the most part - my code runs way faster and I can observe with my System Monitor (ubuntu) that multiple cores are indeed being used. However, ~ 4 of every 5 times I try to run the exact same code, Maple will get stuck on a threaded calculation. If I follow the CPU usage in these instances, I see that one of the CPUs is maxed out at 100%. I am forced to quit Maple and kill the kernel process. Has anyone seen something like this before?

 

Thanks in advance.
