    Jaytie's post in Out Of Memory Error (Fix Common Problems) was marked as the answer   
    Another update and hopefully the solution for my issue:
     
    As mentioned above, the issue reproducedable occured, when connecting with the Hyper Backup Client via rsync to Unraid.
    I guess because of failing reverse lookups the avahi-daemon used all the ram and most of the CPU:
     
    Feb 10 00:55:03 Dockerbox rsync[2997]: connect from 192.168.10.2 (192.168.10.2) Feb 10 00:55:03 Dockerbox rsyncd[2997]: name lookup failed for 192.168.10.2: Name or service not known Feb 10 00:55:03 Dockerbox rsyncd[2997]: connect from UNKNOWN (192.168.10.2)  
    Also Hyper Backup wasn't able to connect during that time. Eventually the system was out of memory killed a process (not always the same) and Hyper Backup connected.
     
    Solution:
     
    I added the line
     
    reverse lookup = no  
    to my
    /boot/custom/etc/rsyncd.conf  
    This results in no more failed name lookups, Hyper Backup connects instantly and Ram usage stays as it should.
     
    I hope this was the main issue. Maybe this will help someone in the future.
