Summary 0000967: Performance issue
Description When runing 3.0.18 Pro with an valid license in our production site it is choking up rather quickly and the response time of our JSP-pages is increasing rapidly to some ten of seconds. Even if we get a log printout that the JNI library is enabled the symptom feels exactly like as when you run a Resin Pro without the JNI enabled on a site with "many" users.

There was no errors during installation and the site is working (responding)normaly (fast) with only one user but as soon as we put some load on the response time increases dramatically. When switching to our previous version 3.0.16 the response time is back to normal under the same amount of load.

Scott,

I asked Niclas to try to enable the select-manager.
This is the result in stdout:

The server starts (processes alive) but does not respond at all from
browser. Do you know why it act like this?

enable-select-manager was initialized in incorrect order.

The temporary workaround is to increase thread-max to something large, like 1024 to handle the keepalive threads.
