[NFS-Ganesha-Support] CEPH RGW and VMWare vSphere 6.7 mdcache_find_keyed_reason

Dear all, I ran into trouble connecting VMWare 6.7 to CEPH cluster exported via RGW and Ganesha. Once the datastore is created, the ganesha thread is stuck at 100% CPU in mdcache_find_keyed_reason, preceeded by pthread mutex lock and unlock. I am at Nautilus, deployed by Ansible, running on latest CentOS 7. The issue appeared in Ganesha 2.7.3 and also in 2.8. Stacktrace from perf top here: https://imgur.com/a/rQ3AKfy I would greatly appreciate any clues or hints on what causes this. Thanks, Martin
