Hello,
IIUC the migration thread should always see valid migration object, as it takes one refcount at the entrance of migration_thread():object_ref(OBJECT(s));
Could the migration have failed before ? in migrate_fd_connect()
So it's not yet clear to me on why the mutex was destroyed, if the main object should still be there; logically it was only destroyed in the finalize phase (migration_instance_finalize), but that should be after migration thread quits and releases the refcount..
Avihai, would you have a reproducer ? or did you keep some logs ? a backtrace maybe ? Thanks, C.
