Jetty & ab issue in quick start?

Martijn Dashorst
Administrator
When I try to run a somewhat longer benchmark with our Quick Start
application, I get strange timeouts while running ab (or siege)

ab -n 100000 -c 4 http://localhost:8080/
This is ApacheBench, Version 2.3 <$Revision: 1826891 $>
Copyright 1996 Adam Twiss, Zeus Technology Ltd
Licensed to The Apache Software Foundation

Benchmarking localhost (be patient)
Completed 10000 requests
apr_socket_recv: Operation timed out (60)
Total of 16347 requests completed

The ab runs always fail at the 16348th request (when you use
concurrency > 1 it will vary around 16348)

I've upgraded/downgraded Wicket (this is still the case with 7.0,
7.10, 8.0, 8.1 and 8.2).

I've upgraded jetty to the latest 9.4 version (9.4.14.v20181114) to no avail.

Running ab on a remote Tomcat server does end normally, so it doesn't
appear to be ab related (also siege exhibits the same behavior on the
local Jetty server).

Can anyone confirm this odd behavior?
