Could not create rrd4j database file error in OH3

Ultimately this is dancing around the golden calf and it happens on all sorts of servers and applications. There is no fundamental ‘solution’ to the problem as there can always be environmental conditions such as e.g. network connectivity loss that result in filling the disk with errors, no matter the application, if zram and how large your disk is. Those parameters only affect how fast or often you hit problems but not if you do at all.

So rotate or just clear your system logs (the ‘permanent’ copies in /opt/zram/log.bind/),
eventually increase size in ztab, then move on with life.
