Hello,
I have a big problem with Apache/Tomcat server. From time to time, some the ajp threads start to "hang". I take listing from JBoss JMX Console - CPU utilization and see that for example 4 ajp workers (during different things, like loading content for page) are taking much more CPU than others, like 10x or 20x more. Furthermore, they should finish relatively quick, because for example they are loading the data for index page.
My question is, can I somehow configure Apache/Tomcat/Connectors so it does not allow for such long operations?
Regards,
Michal

To the best of my knowledge, all these threads should be doing is proxying data between Apache and Tomcat. Are you transmitting large quantities of data?

One of the most odious afflictions that Business has inflicted on the modern English language is "pro-active". Most of the time it's simply redundantly used in place of the simple old word "active". And a good deal of the rest of the time it means "You're not overworked enough yet, so go out and find more!"

No, when I preview some of those request, they for example are loading the page - it is AJAX enabled, but anyway, how to explain the thread is running all the time for 34 hours (and server up time is 38)?
