As far as the OS is concerned, the application (Tomcat) is still using that connection. Therefore it can't be cleaned up. Tomcat has to actively hang up the connection, and the best way to do that is with synchronized timeouts between the reverse proxy and Tomcat. You can try all other kinds of tricks, but the fact of the matter is that the application is still trying to use the socket, so no other component can step-in and kill it. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 Comment: GPGTools - http://gpgtools.org iQIcBAEBCAAGBQJVN7sZAAoJEBzwKT+lPKRYRhkP/j0GBtPH/+/QU2YEgZxbRoJE z2lmWxDrbFNxiYFS5332SvN4bXhG/Khog83CeBM0bg0VLciSxKYqm5J8YziMlrlo omqk3gUiNeViyjsjO5SBW9hxT1qhC1PLdtx7uZ7xUiNmmE24wQ3Gi2edyjyvYDJ0 pzLT+bEp8BjXgm0c6aOONO0PJ+PbyZPeF56PXq6iqn426IhebEUlDP8kxuSh3RwL LQW7tg05bg3yTuP1ZjiwH4gmBfbomJ+xpY6F+zwDkZgk7Cs4okp5/Tr0uTNhsHQM lgGaIZc9SCoqKaMFqWila3RaAnnpqDe1cdg2N44zluIaMkcO94kDSWBuT25t5dGe GBiFG2HGczwyo5MCrx0RgYgLtb2bQ0QZQ8nHzNis8wkNQdHWzziWsvsVQOCnCqL/ 3FOkWUbbJTdmnB8lx84sRcuMsDYQ0BYOYW4W/F2WmSxzBnm7V4NixHG9dD4lZ3vJ fhIO/d0VNOpI+wesZyQg+pwWRHInbigZ0+5A3InOLHW84rWa2qX0wvt6a7rBb0YP gonBY4xbrPTHoXDHH7ZCs3JW+gwstA5avA/Obp45C5LessbduqRPtBvMUZizyZR5 ByPtJcrCvHlFux1fwc7Idj/9seqaYvllyvO6evvhqgYVU3jV2tekOUNuFGDJ8KRt HmrzuiH3cmU1JpT6FSen =XyQw -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
