Looking at the source code that comes from here:

		if (ufds.revents & POLLERR) {
			error("persistent connection experienced an error");
			return false;
		}

So your TCP/IP stack reported a problem with an existing connection.

That's very odd if you're on the same box.

If you are on a large system or putting a lot of small jobs through 
quickly then it's worth checking out the Slurm HTC guide for networking:

Good luck..
