At our site we are fortunate so far to NOT have this problem - is it related to the amount of traffic on the link that has problems? We use Apache httpd 2.0.49; Tomcat 4.1.24; mod-jk 1.2.5 all on Solaris-sparc. Here is a little chart of the configuration data so far from these three examples:
Hangups seen Apache Tomcat mod-jk OS ------------ ------ ------ ------ -- Daniel Gibby 2.0.40 4.1.30 2.0.2 ? Daniel Gibby 2.0.40 4.1.27 2.0.2 ? Beat De Mart 1.3.27 3.3.1 1.2.4 ? No Hangups (so far!)

Requests of our sort never seem to be answered, and we've been asking them for months. Actually, by being answered I'm not saying that people don't post replies, I just mean that I don't know of anyone who has fixed this issue on their system. It sure sounds like the same issue that I'm having with mod_jk2 2.0.2, apache 2.0.40, tomcat 4.1.30 or tomcat 4.1.27... but I can't be sure that it is the same issue. My bet is that most of the tomcat developers don't use connectors because they would rather keep things stable, and introducing apache into the mix just means one more point of failure. Sorry I can't be of more help right now. I've tried using JMeter to reproduce my lockups, and that hasn't helped me yet. Is there someone out there who would like to be paid to run a profiler on some of my applications? Please contact me off-list, and if you can solve my issue, I'll post the results to the list... I'm in contact with two or three people from this list that are having the same type of issues, and more requests for help come into the list weekly. We'd all be happy for the help.
