Subject RE: jk2_init() Can't find child xxxx in none of the 1024 scorebo ard slots
Date Thu, 06 Nov 2003 15:41:58 GMT
I have similar problem upgrading to 4.1.29. I figured out it is connector
4.1.29 that causes the problem. So I use tomcat 4.1.29 + connector 4.1.24.

Hi Chong,

Load balancing is just a change in the configuration file that’s all,  I
think it has to have something to do with the compilation, what lib was it
that you were missing? Perhaps that is our problem too.

Hi Tony,

I can't help you with the load balanced configuration because I'm not
using load balancing (yet). I was using the older version of mod_jk2
just fine too. When the rpm file disappeared from the download site, I
had to compile using the latest version, and that is when my problems
started.

 From the description of your problem, I would say that something is
wrong either with the file you downloaded (corrupted download?) or your
compilation failed somewhere. The bad thing about jk2's compile is that
it doesn't give you many errors when it fails, and if you don't look too
closely, the failure can be invisible. I spent 2 days compiling and
re-compiling initially, because I was missing a library file (and didn't
even know it).

I'm investigating this on my end too. Has anybody else on this list
tried and succeeded with Tomcat 4.1.29/Apache 2.0.47/mod_jk2/Linux ?

Regards,
pascal chong
