Hi Konstantin,
osd_target_transaction_size should control that.
I've heard of it being raized to 150 with no obvious issues. Going
beyond is at your own risk. So I'd suggest to apply incremental increase
if needed.
Thanks,
Igor

I recall a couple of cases when permanent osdmap epoch growth has
been filling OSD with relevant osd map info. Which could be tricky to
catch.
Please run 'ceph tell osd.N status" for a couple of affected OSDs
twice within e.g. 10 min interval.
Then check the delta between oldest_map and newest_map fields -
neither the delta should be very large (hundreds of thousands) nor it
should grow rapidly within the observed interval.
Side question by topic. What is option controls how much maps to
prune? Currently I need to trim 1M osdmaps, but when new map issued,
only 30 old maps are removed. What option controls value=30?
Thanks,
