Hello,

We are writing to ceph via librados C API  . Testing with rados no issues.  

The same we tested with Jewel/kraken without any issue. Need your view how to debug this issue?

maybe similar to http://tracker.ceph.com/issues/21180? It seems it was resolved for me with mentioned fix. You could apply mentioned config options and see if it helps (and build newer version, if able).

I think you may be missing debug packages as there are no thread names.
