hey hey forumguest, actually we use the standard-pool-size-values (min 2, max
5, timeout 900sec) which seems to be OK for us. The application will run for
a couple of hours or days, sometimes weeks without any problem. and after an
undefined timeperiod more and more http-pool-threads stuck in something like
an infinite loop or something else. jstack will show something like this for
the correspondent threads: "http-thread-pool-80(1)" daemon prio=10
