[ceph-users] [ceph-ansible][radosgw]: s3 key regenration issue

Dear All, I am getting 500 internal server error after deleting and creating new access and secret keys. I am able to access my buckets and and its data using new keys from S3cmd utility. but it seems ceph MGR keep cache and throwing 500 internal server error I am trying to get meta data from CEPH dashboard. But when I do ceph mgr fail and move the ceph dashboard to another MGR then it starts working fine again. Is there a way I can clear cache of MGR or is the any bug in ceph for regeneration of S3 access keys? Regards, Danish
