I believe then this is going to be related to the automatic updater, which tries to get the most recent plugin version once a day. But since it was not able to successfully retrieve it, it tries again every time. I'm not sure why it is looping though, as there is a 2 second timeout set, which is also default for WordPress – and besides that, the remote blocking should do the trick here as well, as it uses the same built-in function as the others.
Can you please add temporary FTP details as well? I would like to debug through the code to see where this is originating from exactly.Best,
