Research direction
Start by reproducing the issue with trace logging enabled and observe log rotation while other threads, including GRPC, are active. Trace the Poco logger rotation path and identify why logging blocks for several seconds. Done means logs continue to appear promptly during rotation, with coverage for the reported behavior if the project provides relevant tests.
