pid xxxx (progname), jid 0, uid 0, was killed: failed to reclaim memory

Hi List,

I noticed that on my aarch64 boards I recently get a lot of 'pid xxxx 
(progname), jid 0, uid 0, was killed: failed to reclaim memory' messages 
in syslog.

This happens on a rockpro64 as well as a raspberry pi 3b, both running 
13.2. None of the boards is near its memory capacity (more like less 
than 50% used).

It started on the rockpro64 first, were i did a bit of fiddling, e.g. 
en/disable swap, replace zfs with ufs, etc. nothing helped in the end. I 
thought the board might be defective but now i start seeing the same 
thing on the raspi as well.

Any ideas what this could be or how to debug this further?


Thanks & best regards
