This issue is caused when calling to "lago ovirt serve" (which starts the repo server) as a subprocess,  and not making sure to kill it when it's not needed anymore (or on failure).

In the past, VDSM's check patch was coded like this, but we fixed it. Could be that the same bug exists in another suite.

Evgheni, can you specify a slave that had this issue?

I agree with Barak - checked the slave that was failing and there was a process still listening to port 8585. 
The slave was put offline the slave but attempting to run the job on a different one caused the exact same error.
As more slaves are affected this may be a lago bug. No changes were made on slaves this week.

looks like there might be a lago localrepo process process left up on the slave from a previous run

Evgheni,
Was there any change recently to Lago slaves?

I attempted to run manual OST twice and both failed with below issue.
Can someone take a look?

Thanks,
