mod_jk validate failed / factory failed error
Can anyone give me a hint what makes the following mod_jk error.
I use isapi_redirect.dll 1.2.14 with IIS 6.0 on Windows 2003.
The log is :
[Fri Aug 18 14:57:31 2006] [error] jk_worker.c (158): validate failed for ajp13

I have my log level 'emerge' so the log does not appear.
Anyway, It's better to describe the meaning of 'retries=1' clearly in
connector doc.

Okay, I'll try it.

You mean the 'uriworkermap.properties' file in my case (IIS 6.0)?

Right, you should have at least a warning in the log that the
retries was set to 1 (without retry).
Anyhow, the message:
[error] jk_worker.c (158): validate failed for ajp13
means that you have some error in the cofiguration.
Try to rename the loadbalancer from ajp13 to something
else. ajp13 is reserved single worker name, so that might
be the reason (have no time to validate :)
so try:
worker.list=ajp13b
...
worker.ajp13b.balanced_workers=swuwpa03_servlet_mdscm,swuwpa04_servlet_mdscm,swuwpa03_servlet_mdscm2,swuwpa04_servlet_mdscm2
worker.ajp13b.sticky_session=false
worker.ajp13b.type=lb
And of course modify the JkMount's

Mladen.

Thanks for your quick response.
I have another question.
In tomcat-connector document
(http://tomcat.apache.org/connectors-doc/config/workers.html)
, I can not find any clue of syntax error about 'retries=0'.
Isn't zero valid value when I don't want to retry?
What value should I use when I don't want to retry?
It feel that the syntax error ('retries=0') is NOT the direct reason
of 'validate failed for XXX' or 'factory failed lb for XXX' error,
because the error shows up occasionally.

Syntax error. retries=0
BTW, 1.2.15 is broken. Use at least 1.2.16

I can load your workers.properties configuration using 1.2.18 (but I
Used Apache 2 and Solaris). The validate method code says, that either
there should be a message of level "error" before the first one you
copied to your mail (and that one will give us a better indication about
what's wrong), or memory allocation failed. Maybe you can set your log
level to trace and post the full log.

Rainer
