I would suspect heat. Flash is very CPU intensive.

That's a good idea, thanx. I will put some heat monitor widget and monitor that. But if that is the case, is there some workaround? Like limiting the priority or setting different overheating strategy?

There are two things. One, is that a computer should be able to disipate addequately the heat generated at full continuous load. But this does not always happen, typically because of problems (like dust), but also by design: the machine is is not designed for full continuous load on warm weather, worst case scenario, but sporadic, short bursts. And two, it is my opinion, often stated, that the operating system should monitor the temperature of the CPU and take measures if it overheats, to avoid crashing. What measures? Throttling. First step is to slow the clock. Second is to insert iddle instructions. You can limit a process: cpulimit (1) - limits the CPU usage of a process Searching for that one I just found this other: cer@Telcontar:~> apropos cpupower cpupower (1) - Shows and sets processor power related values cpupower-frequency-info (1) - (unknown subject) cpupower-frequency-set (1) - (unknown subject) cpupower-info (1) - Shows processor power related kernel or hardware configurations cpupower-monitor (1) - Report processor frequency and idle statistics cpupower-set (1) - Set processor power related kernel or hardware configurations cer@Telcontar:~> But of these I only see the manuals, not the tools :-?
