Tomcat + Apache (mod_jk and more)

Hi!

I have three questions:

1). My mod_jk does not appear to run correctly. Sometimes it works and
I get connected to tomcat as expected, but most of the time it times
out. When I look at the mod_jk.log I set up, I get something like this:

[Sun May 01 20:37:03 2005] worker1 localhost 0.024238
[Sun May 01 20:37:12 2005] worker1 localhost 0.012673

But when I look in the apache errors.log I see this:

[Sun May 01 20:37:12 2005] [error] (13)Permission denied:
apr_global_mutex_lock(jk_log_lock) failed[Sun May 01 20:37:12 2005]
[notice] child pid 373 exit signal Bus error (10)

The timing corresponds with the "not working" of things.

Any ideas?

2). When I restart the Tomcat server itself, including rebooting my
machine, none of the application containers I have installed with .war
files start automatically. I have go into the manager app to start
them. I think I know how to fix this for servlets, but how do you do it
for JSP/bean based stuff?

3). The Tomcat I installed says you need Java 1.5, otherwise you have
to install some compatibility files. I have Java 1.4.2, and except for
the above issues, it seems to work. Is this unusual, or will I run into
problems at some point?
