Dear community,

We are new to lava and try to use lava in our android test. We have issues when test iperf.

The job log for dragonboard-410c is:

NOTE: it looks hung at this step, the job can't continue.

The job log for ssh is:

It seems that one node can't receive server-ready from another node, what's wrong with my job? Please help!

Thanks,
