My best guess here is that the resource manager is still trying to connect to the JobManager which failed - after all, how should it know whether this is a temporary network failure or a permanent failure?!
If, after your new JobManager starts, the errors stop as well, I'd say, you don't have to worry about the messages. Till (cc'd) may elaborate a bit more on this.
