@rtjdamen hey there, did you ever modify in the POOL advanced tab at the bottom the BACKUP network & MIGRATION network ? fiddle with these, note what they are actually set, and change them if possible between each change, check your SR stats @florent could explain better how SR stats use the backup network to get the RRDs... I guess you have stalled RRD tasks too ? in tasks list ?

Exactly and that's what does the Rolling Pool Update feature

I also added windows build so that people can help with testing also on windows. It's a static build, no need for installer, just single zipped .exe file. No dependencies.
