Hi David, This is strange but the issue stopped when i changed io_uring to threads. Would that make any sense ? We did also few other smaller things but honestly issues stopped. Was it fixed or maybe Async IO could cause it ? (The qcow2 image is on fuse mounting). I am not certain but if that makes any sense, should i report this to someone working on io_uring or it should have nothing to do with that bug ?
