OK, I did some tests today, here are the logs:
ftp://shulyaka.org.ru/pub/memlog.tar.bz2

I have rebooted the phone to get clear results, started WiFi, Midori
and transmission-daemon and run the following script:

#!/bin/bash
while true; do
    STAMP=`date +%H:%M:%S`
    ps axuf > ps.$STAMP
    free > free.$STAMP
    df -h > df.$STAMP

    sleep 300
done

It writes output of `ps auxf`, `free` and `df -h` to a corresponding
file every 5 minutes.

The phone could survive for 4 hours. When I look at the phone after
about 3 hrs and 45 min the Xorg (along with vala-terminal and my
script) was already killed (the last log entry was at 3:40). However I
still was able to ssh into the phone and get some final data manually
(named *.last).
On the phone screen I saw text console with following messages:

What additional info I can gather?
