The workload is synthetic: /home/cel/bin/iozone -M -+u -i0 -i1 -s1g -r8k -t16 -c The client is a 12-core Xeon system. I'm seeing all kinds of symptoms: - memory leaks: bvec and enc_pages are leaking - EBADMSG is reported to user space - data corruption - connect deadlocks resulting in a mount hang - invalid soft IRQ receive buffer warnings -- Chuck Lever
