I still have not looked at the log messages, but I see the dbus thread waiting for the upcall thread to complete when an export is removed. Is there is a time limit on how the upcall thread gets blocked? In GPFS fsal, we actually send a command to return the upcall thread with (THREAD_STOP) and then wait for the upcall thread. Regards, Malahal. PS: GPFS has only one upcall thread for the entire file system image (not for each export).
