In my ceph version 14.2.5.ceph radosgw mem is high (4.6g use top command).when I write 20m. I noticed dump_mempools's buffer_anon is very high (3-4g)in testing,after test,the buffer_anon has been release(about10m). but rgw mem is still high(about 4.6g).So i think maybe some memleak occurred in rgw. Could someone can help me? or Could someone tell me how to tune rgw-memory?
