I am pretty sure I can handle that. From the timestamps it looks like it
always happens when large amounts of data come in from rsyncs. These are
cronjobs, so I got the time.
Question: I just checked "slabtop -o" and found out it outputs exactly
nothing, whereas slabtop (without option -o) shows up just like (process) top
with lots of lines. Can you clarify why there is no console output at all with
option -o ?

Do you know what version should definitely be not affected? I can check one
kernel version per day, can you name a list which versions to check out?
