JK2 apache2 log errors
Can anyone explain the following errors to me? This is from the error_log
file of the httpd (apache2) server.
Red Hat Linux 9
Red Hat httpd (apache2) 2.0.40-21
Sun JDK j2sdk1.4.2 (beta)
Tomcat jakarta-tomcat-4.1.24
JK2 Connector made with jakarta-tomcat-connectors-4.1.24-src
NOTE: When I start up tomcat and then appache, it works; I can access both
the root page of apache and I can access the tomcat examples, but why are
these errors writen to the apache log file???? Thanks.

Unlike Apache, Tomcat does not start up instantly...it needs time to do so.

Hello:
How do I enable the jkstatus page? I have not seen any docs on it.
Thanks,

In the process of digging through the mod_jk2 source code to solve my own
problem (which still hasn't happened), I came across extensive references to
the "scoreboard". It is a place in a workerEnv data structure that holds
the process ID of a child process. I'm not sure about who spawns what
where, but at least it appears Apache spawns off the jk2 stuff, which then
goes off and spawns worker threads. It appears the "scoreboard is a place
in the worker environment to keep track of some of the housekeeping that
goes on with these threads.
I've only looked at it for about an hour, so this could be all wrong, but
that's what it looks like.

Scoreboard refers to the "jkstatus" context which, if you are using the
default worker2.properties that came with the rpm package for mod_jk2,
you will see a section on. If you have "jkstatus" enabled, you will be
able to see the status of your mod_jk2 connector by going to the URL :
http://domain.com/jkstatus

As far as I know, no, the two aren't related. My sysadmin had commented
the stuff about a Scoreboard directive in httpd.conf out, and I'm not
sure if I understand what it's intended to be used for. Perhaps there is
someone out there more familiar with it?
Sorry!

Thanks for your reply.
What does it mean when it says, "Can't find child 2954 in scoreboard?" Is
the 'scoreboard' have something to do with the shm.file?

I'm not 100% sure about this, but I saw the same thing on my Solaris box
using jk2; I *think* you can safely disregard that "mod_jk child init 1
-2". As far as that jk2_init goes, I would get that if I started up
Apache before Tomcat had completed starting - I just got used to doing
something else in between the start of one and the start of the other to
avoid that error...
