Your problem description is very similar to MDEV-31410. You could SET GLOBAL innodb_max_dirty_pages_pct_lwm=0.001; to make the InnoDB log checkpoint advance more often. This should become unnnecessary once MDEV-30000 has been fixed.

To my knowledge, FLUSH LOGS and PURGE LOGS have nothing to do with the InnoDB storage engine.

this seems to have fixed the problem. Thanks a lot for helping. Might there be any negative impact of this setting? Which?
