Sorry. I don't have any similar experience before.
>From the messages, I guess that you have your JServ
started by Apache (i.e. "ApJServManual off" in the
.conf file). The Apache process keeps monitoring the
JServ and comunicate with it via ajp12 in a specific
time interval to ensure that it's alive. As your
thread is a long running one, the JServ (running on
VM) does not respond to Apache process before timeout;
the Apache process considered that your VM was dead
and start another one for you. I found that there is a
parameter "ApJServVMTimeout" in jserv.conf, its
default value is 10 sec. I don't know whether this
parameter is the key of your problem. But I think it
should be a parameter related problem.
By the way, if you cannot find any solution, is it
possible for servlets to write some dummy output to
the Apache process periodically, let's say
out.println("") and then out.flush() , such that it
won't wait too long and considered the JServ is dead
(i.e. keep some traffic in ajp12). I know that it
absolutely a dirty trick and it may not work. But it
may better than nothing.
Hope this help.

Dagan
