Hi folks,
I'm working with recent builds/installations of
Apache 2.2.22 with mod_jk 1.2.37 on MacOSX 10.4.11/PPC
Apache 2.2.22 with mod_jk 1.2.37 on MacOSX 10.8.2/x86_64
connecting to Tomcat 5.5.7 (from binary distribution) running on
MacOSX 10.4.11.
What I am finding is lots of log entries such as this one in /var/log/
apache2/mod_jk.log:
[Thu Nov 29 12:17:14.422 2012] [38496:140733193388032] [warn]
map_uri_to_worker_ext::jk_uri_worker_map.c (1057): Uri * is invalid.
Uri must start with /
corresponding to this one in /var/log/apache2/access_log:
::1 - - [29/Nov/2012:12:17:14 +0000] - - - "OPTIONS * HTTP/1.0" 200 -
"-" "Apache/2.2.22 (Unix) DAV/2 mod_jk/1.2.37 mod_ssl/2.2.22 OpenSSL/
0.9.8x (internal dummy connection)"
My understanding is that this is the Apache master instance running
as root is polling its spare/worker processes to check that they're
alive and I have tracked this down to server/mpm_common.c in the
Apache 2.2 sources.
I'm not an Apache internals expert. I'm not really even that good at
configuring Apache. I have:
<IfModule jk_module>
JkWorkersFile /etc/apache2/workers.properties
JkShmFile /private/var/run/jk-apache2.shm
JkLogFile /private/var/log/apache2/mod_jk.log
JkLogLevel info
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories
JkRequestLogFormat "%w %V %T %s %r"
JKMount "/TomcatApplications/*" worker1
JkMountCopy All
</IfModule>
so I don't see how the heartbeat request is being processed by the
jk_module handler. Possibly my diligent use of Google to find how to
configure apache 2.2 to stop this has not been diligent enough.
Suggestions for additional Apache configuration directives are welcome.
Would it be reasonable to change the sources for mod_jk to not log a
warning when the URI is * and the method is OPTIONS and the remote
address is localhost?
