Actual results: --------------- Ganesha crashes and dumps core. Expected results: ----------------- No crash. Additional info: ----------------- *Client and Server OS* : RHEL 7.3
This is a case of an extra ref taken or a failure to deref. Where is the source that corresponds to nfs-ganesha-2.4.1-5.el7rhgs? What is the workload that is being run?
