D'oh. In your original post, did you include your entire
workers.properties file? Also, can you post all your Jk* directives you
have active in your httpd configuration?
The code that performs validation of the worker is found in
native/common/jk_lb_worker.c:
static int JK_METHOD validate(jk_worker_t *pThis,
jk_map_t *props,
jk_worker_env_t *we, jk_logger_t *l)

This occurs on line 1536 (in mod_jk 1.2.30), in this neighborhood:

This looks like it might be a shared memory allocation error. Once you
get into the jk_shm and jk_pool code, there's no debug logging of any
kind :(
You might have to hack-in some debug logging if Rainer or Mladen can't
comment further. Are you comfortable compiling your own mod_jk? It looks
like compiling with DEBUG #defined to something will at least get you
jk_dump_pool calls when shared memory fails to be allocated.
