[Bug 55395] New: AH01382: Request body read timeout with IE 8 or 9
|

https://issues.apache.org/bugzilla/show_bug.cgi?id=55395
Bug ID: 55395
Summary: AH01382: Request body read timeout with IE 8 or 9
Product: Apache httpd-2
Version: 2.4.4
Hardware: Other
OS: Linux
Status: NEW
Severity: normal
Priority: P2
Component: mod_proxy_balancer
Assignee: bugs [at] httpd
Reporter: cthiele [at] mccarthy
We are running Apache 2.4.4 with SSL, mod_proxy_ajp to balance 4 tomcat 7
instances. We recently upgraded from Red Hat Linux 4 to Oracle Linux 5.8.
After upgrading we saw a significant increase 4-5 times as many 400 errors from
IE 8 and IE 9 in our logs. No 400 errors from firefox or chrome. The issue is
extremely difficult to reproduce. It took me 3 hours of just constant clicking
from a remote site to be able to reproduce. I am not able to reproduce from
our office which is where our data center is located. Latency does appear to
be a factor.
Below is a debug log when I was able to reproduce. The line AH01382: Request
body read timeout is where the issue occurs. We've turned down the ready body
timeout to 20 seconds which has helped with the hanging behavior.
Any reports of similar issues or advice on how to fix or at least reduce the
frequency of the issue?
