Hmm, I cannot reproduce this

Same when running in foreground and doing operations from another console


cqe unique: 4, opcode: GETATTR (3), nodeid: 1, insize: 16, pid: 732
     unique: 4, result=104
cqe unique: 6, opcode: STATFS (17), nodeid: 1, insize: 0, pid: 732
     unique: 6, result=80


In order to check it is not a recursion issue I also switched my VM to
one core - still no issue. What is your setup?
Also, I'm still on 6.10, I want to send out v5 with separated headers
later this week and next week v6 (and maybe without RFC) for 6.12 next
week.


Thanks,
