Hi, Did we really need to have a linger set in Ajp13 ? In Ajp13Interceptor there is a : super.setSoLinger(100); Which make us that we'll wait up to 100s before releasing the socket if data must be sent to remote (may be a restarted Apache...) or better drop the all wait before close : super.setSoLinger(0); Thanks for your ligth here, I'm still looking for the ajp13 bugs under heavy-load and couldn't reproduce these bug.
