High CPU usage for process ansible command md and mdx

Hi, I am new to ansible but and started to have a weird issue with CPU load.

I am running on debian 9 with ansible 2.4 from backports (the same issue was on 2.2). This is the load I am getting straight after booting (no playbooks or anything):

PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
1279 ansible 20 0 381024 11424 5940 S 99.0 0.1 6:08.56 mdx
1278 ansible 20 0 237704 4600 2376 S 98.7 0.1 6:08.92 md

There is nothing in log and my playbooks when played are ok (just take forever as the CPU is flt out).

I have found various bug reports but none seem to fit the symptoms I am having. The only theory I have is that it might be something in the general config of ansible but so far I haven’t fond anything of interest.

Any advice would be greatly appreciated.

sorry just realised this is a user called ansible rather than process so this is something totally different and unrelated
