It's a bit of a kludge, but just failing the active mgr on a regular
schedule works around this issue (which we see also on our 17.2.5
cluster). We just have a cron job that fails the active mgr every 24
hours - it seems to get up to ~30G, then drop back to 10-15G once it
goes to backup mode.

there was a thread [1] just a few weeks ago. Which mgr modules are
enabled in your case? Also the mgr caps seem to be relevant here.

thanks for the hint and link. We actually use the restful module and
modified the mgr caps to use zabbix monitoring. I now have reverted
the mgr caps to default and will observe the memory usage. I think w
ran into the same issue here.
Thanks
Tobias
