Re: httpd 2.4.39 mod_reqtimeout causes large uploads to fail

Very likely a duplicate of

https://bz.apache.org/bugzilla/show_bug.cgi?id=63325

(regression in 2.4.39) with the fix

https://svn.apache.org/viewvc?view=revision&revision=1859376

which will be part of the next version 2.4.40.

You can try that patch if you like. 2.4.40 is not far away, maybe next week.

It is not yet in the published Changelog, because that is for 2.4.39 and this change will be in 2.4.40. The new item will be:

  *) mod_reqtimeout: Fix default rates missing (not applied) in 2.4.39.
     PR 63325. [Yann Ylavic]

A recent change to mod_reqtimeout (2.4.39) is causing large uploads to sporadically fail on my production server with a client error:

|ajp_read_into_msg_buff::jk_ajp_common.c (1553): (main_ajp13_worker) receiving data from client failed. Connection aborted or network problems|

This is happening partway though chunked PUT requests to mod_jk.

 From the changelog:

  *) mod_reqtimeout: Allow to configure (TLS-)handshake timeouts.

     PR 61310. [Yann Ylavic]


My short-term workarounds for this problem are:

a. Downgrade to httpd-2.4.38 (not recommended, see changelog for 7 CVEs)

b. Comment out the LoadModule line for mod_reqtimeout

For details, please see:

https://serverfault.com/q/972680/293818

Questions:

1. Was there any accompanying documentation for this change?

2. What configuration options are available to adjust this timeout?

3. Why does this result in a client error instead of a timeout error?

4. Has anyone else experienced this problem?
