It should be safe to ignore them though it's not a solution.

I had seen those for about half a year on amd64/6 and sometimes it's
not only 3 lines but a few hundred. Also 1G RAM here.

For me also my backup runs during the hours this sometimes happens.
Was was not able to track it down to one specific event.

I tried to capture memory usage during that time but could not find
anything (maybe I haven't checked correctly).

In case you find out the casue of this I'd be happy to test changes:)
