Hi,
It happened again, and I noticed it in time to record a few
stats... But I fear that this is not enough to actually
debug the problem. What else could I do if this happenes
again? In this particular case, the load dropped back to
0.0 after a few minutes, for no apparent reason.
BTW, this is some 3-stable (not the newest, but I watched
the same behaviour on all kinds of different versions).
