(The above was edited to remove irrelevant IP addresses and sort by port.) The fact that *none* of the ports match would suggest (but not prove) that someone in the middle is closing the connections, and not telling either end about it. > - why do the 11 threads in the httpd o/p show port > 21069 in foreign addr. They're for a different IP address. > - currently I do have connectionTimeout set in server.xml. > I will need to wait until night to reset that.
