Description Chris Duryee 2009-05-20 20:50:30 UTC 
Description of problem:

In one of our environments, we have an apache with prefork MPM that serves mod_jk requests as well as CGI.

When we upgraded to mod_jk 1.2.28, we turned on JkWatchdogInterval. This caused mod_jk to eventually hang all of the worker processes.

After consulting with Sam Mendenhall, it turns out that JkWatchdogInterval is incompatible with prefork.

Can you add a check to ignore the JkWatchdogInterval flag (and perhaps print a warning) if it's set on a prefork apache? 

Version-Release number of selected component (if applicable): 1.2.28
