Mturk,

Thanks for your reply.

My objection was not exactly technical.
As I said I already did the tuning you are suggesting, when the default was
too few connections, not too many. 
Still, I would rather have a too low default value on JK and get a
corresponding error message on Tomcat asking to raise maxThreads, which was
happening in the past.
A default 250 connections on the JK side on IIS does not exactly force
anyone to fine tune anything, and if too many connections are the reason of
my problem I would still suggest to lower this number.

Though, so far it is not clear at all that this is the cause. :-)

Thanks,
br1
