Hi, We've had PULL replicas stop replicating a couple of times in Solr 7.x. Restarting Solr has got it going again. No errors in logs, and I've been unable to reproduce the issue at will. At least once it happened when I reloaded a collection, but other times that hasn't caused any issues.
I'll make a note to check state.json next time we encounter the situation to see if I can see what you reported.
