[jetty-users] exception upgrading jetty

[Mattia Merzi <mattia.merzi@xxxxxxxxx>]

Hi everyone,

I've just upgraded jetty version from 7.3.0 to 7.6.1
and we started to see this exception, more ore less
1 every 2 or 3 HTTP requests:

java.net.SocketException: Transport endpoint is not connected

Jetty is behind an apache httpd with mod_proxy + mod_proxy_http; not every time,
but 1 out of 100 requests, associated with the java exception, the
client receives an
HTTP 502 (proxy error) from the apache httpd (apache httpd is 2.2.17); mod_proxy
is configured with no keep-alive and a very long timeout, the server
handles about
10~15 requests/sec.

If you need more details, let me know.

Greetings,

Mattia.
