In the mongod-side disagg page-server reader, the code that acquires rate-limiter tokens before a page fetch retries in a tight loop until it gets a token, and it logs a WARNING on every iteration of that loop. When the per-mongod egress rate limiter is saturated the loop spins and the warning fires continuously. There is no rate limiting or sampling on the log line itself, so a single node can emit tens of thousands of identical warnings per second.
