Quite exactly at 00:30. Below is my crontab. I don't expect, however,
that the main problem here is in the crons - since even now (daytime)
there is only 17mb free memory, and at times during the day running top
showed 6mb free, even though there is not much CPU use or traffic. But
yes, the actual low memory report came 0:30. The GUI calculates swap as
memory, so now it showes me 50% free.
