Severity: critical
Priority: P2
Component: All
Assignee: bugs@httpd.apache.org
Reporter: tiziano.digennaro@gmail.com
Target Milestone: ---
In our production system we have a custom compiled version of apache 2.2.31 on
a debian machine with OpenSSL 1.0.1u
Server version: Apache/2.2.31 (Unix)
Server built: Oct 31 2016 13:51:59
Server's Module Magic Number: 20051115:40
Server loaded: APR 1.5.2, APR-Util 1.5.4
Compiled using: APR 1.5.2, APR-Util 1.5.4
Architecture: 64-bit
Server MPM: Worker
threaded: yes (fixed thread count)
forked: yes (variable process count)
Server compiled with....
-D APACHE_MPM_DIR="server/mpm/worker"
-D APR_HAS_SENDFILE
-D APR_HAS_MMAP
-D APR_HAVE_IPV6 (IPv4-mapped addresses enabled)
-D APR_USE_SYSVSEM_SERIALIZE
-D APR_USE_PTHREAD_SERIALIZE
-D SINGLE_LISTEN_UNSERIALIZED_ACCEPT
-D APR_HAS_OTHER_CHILD
-D AP_HAVE_RELIABLE_PIPED_LOGS
-D DYNAMIC_MODULE_LIMIT=128
-D HTTPD_ROOT="/opt/loadbalancer/apache"
-D SUEXEC_BIN="/opt/loadbalancer/apache/bin/suexec"

-D DEFAULT_ERRORLOG="logs/error_log"
-D AP_TYPES_CONFIG_FILE="conf/mime.types"
-D SERVER_CONFIG_FILE="conf/httpd.conf"
Sometimes during high load we got from the client and ssl handshake failure.
I was able to reproduce the bug with apache banchmark. It always happens above
4 as concurrency level (ab -c 5 -n 2000 -p post.body)
Here the tcpdump that show after the Change Cipher Spec it always happens this
issue.

You'll have to find some more data here -- error log, some optional feature
that casues the issue, or some sign of a regression.

--- Comment #3 from William A. Rowe Jr. <wr...@apache.org> ---
Please help us to refine our list of open and current defects; this is a mass
update of old and inactive Bugzilla reports which reflect user error, already
resolved defects, and still-existing defects in httpd.
As repeatedly announced, the Apache HTTP Server Project has discontinued all
development and patch review of the 2.2.x series of releases. The final release
2.2.34 was published in July 2017, and no further evaluation of bug reports or
security risks will be considered or published for 2.2.x releases. All reports
older than 2.4.x have been updated to status RESOLVED/LATER; no further action
is expected unless the report still applies to a current version of httpd.
If your report represented a question or confusion about how to use an httpd
feature, an unexpected server behavior, problems building or installing httpd,
or working with an external component (a third party module, browser etc.) we
ask you to start by bringing your question to the User Support and Discussion
mailing list, see [https://httpd.apache.org/lists.html#http-users] for details.
Include a link to this Bugzilla report for completeness with your question.
If your report was clearly a defect in httpd or a feature request, we ask that
you retest using a modern httpd release (2.4.33 or later) released in the past
year. If it can be reproduced, please reopen this bug and change the Version
field above to the httpd version you have reconfirmed with.
Your help in identifying defects or enhancements still applicable to the
current httpd server software release is greatly appreciated.
