Sure, as soon as I understand the problem completely, which I did not so
far.

Though I keep thinking it is probably better to choose a small default than
a large one in this case.

Well, no, maybe we need to go some steps back.
I am talking about JK workers (isapi plugin workers), and I have no IIS
workers: the problem is on IIS 5. 
As I said I have a connection_pool_size currently set to 300 on the JK
worker (IIS side) and a matching maxThreads set to 300 on the Tomcat side. 

What you are telling me is that I don't have 300 threads on this IIS/JK
worker side, but simply (a maximum of) 300 tcp connections to the Tomcat
instance, is this right? So maybe I am just out of connections..

Though it would fit better on "connections" page more than on a "timeouts"
page. :-)

Thanks for the help!
