It is strange. It should occur once (after 30 seconds delay). Maybe shutting down the server socket is not enough to break the Acceptor thread... I think a thread dump is needed to diagnose this. (Especially what Apr Acceptor thread is doing). Your report sounds as if it is reproducible. Missing message is certainly a small bug. > > Tomcat 7.0.21 32-bit windows zip starting and stopping via the startup and > shutdown scripts doesn't give me this problem. > > Any ideas what could be wrong?
