Bug ID: 58565
Summary: Connection will be closed on slow file download with
non blocking http protocol
Product: Tomcat 8
Version: 8.0.28
Hardware: PC
OS: All
Status: NEW
Severity: major
Priority: P2
Component: Connectors
Assignee: [email protected]
Reporter: [email protected]
Problem:
Setup Tomcat (8.0.28) with default settings. Copy a file in a webapp e.g.
webapps/root and download the file with limited speed to simulate a slow modem
download.
wget http://xxx.xxx.xxx.xxx:8080/xxxxxxx/7.zip --limit-rate=1k
Connection is closed always after 6minutes and 24seconds
e.g:
Saving to: ‘7.zip’
7.zip 0%[ ] 767.99K 1.00KB/s in 6m 24s
2015-10-28 17:27:39 (1024 B/s) - Connection closed at byte 786426. Retrying.
if i change the protocol to an old blocking protocol:
protocol="org.apache.coyote.http11.Http11Protocol"
everything is fine and the download will complete with slow speed.
If the change the speed (with protocol HTTP/1.1) the time after the connection
is closed is different (e.g. for 7kb/sec it will always close after 3minutes
and 21sec).
If the speed is 8kb/sec or higher the download is stable with both protocols.
