Thank you for your answer.

I am alreay using v2.8.2.16.gfc7bf0-RELEASE. Isn't it the latest 2.8.x
kernel?

Maybe you are right about misinterpretation of memory
statistics, because what I see in "top" now is:

== top ==
Memory: 2978M Active, 1482M Inact, 1171M Wired, 215M Cache, 605M Buf,
62M Free
== top ==

Total amount is 6513M which is more than I have:

== dmesg.boot ==
real memory  = 6440680448 (6142 MB)
avail memory = 6037917696 (5758 MB)
== dmesg.boot ==

So now I'm not sure whether the number less than 6G indicates that
anything
is wrong ether.

Anyway I started to collect memory and swap statistics with munin,
so that next time it hangs I will see what happened in details.
