Hey Rafael,

If it helps any, I have noticed that this issue generally occurs after
several runs of tempest tests. I run all smoke tests. I have been always
suspicious that some new test got added which is not cleaning up
afterwards.  Can you point me to which tempest test corresponds to
test_boot_pattern? I can do some investigation as well.

Thanks
