This happens due to intensive I/O. You need to change swapiness and other parameters.
Issue this commands as root:

Hi everybody;
I'm doing some tests with my n900 and installed EasyDebian and also created a chrooted Gentoo image to play with it.
My problem comes when my N900 is compiling very huge files or is uncomprising some huge files (KDE packages on EasyDebian or Qt source code in Gentoo)... When my N900 is working on that kind of tasks, it suddenly reboots and if I try to repeat the process, the reboot occurs again in the same moment or when compiling/uncomprising other stuff.
So, did someone have some similar behavior on his/her N900? Is it a known behavior? (I am thinking the excessive heat is causing such a problem) If it is, did someone find some workaround on this?
Thanks in advance.
BTW, which Gentoo are you using?

It's related to overclocking (just search here for "smart reflex") - some people have great success especially improving battery life, but for some like me it can cause random reboots etc.

Smart Reflex is only a problem when overclocking/undervolting, with stock PR1.3 I had no problem.

Sorry, I should've made myself a bit more clear as well. The reason for asking is that I do indeed tend to have SR running, on PR1.3 (It does indeed improve my battery life), but I did not see the connection to the reboots (I know for many SR causes random reboots, but I don't think the sudden reboots from compiling are the same as those caused by SR) or swappiness. Hence the request for elaboration.

But I agree - a reboot at the same point in a certain command doesn't sound like smart reflex problems...
