Hi Load of IM requests goes through squid proxy and most functionalities of IM handle by url_redirector program.Redirector program functioning properly. But after some times , like after 8 hours or some thing that url redirector program doesn't work. In my suid.conf url_rewrite_children 5 , Isn't this satisfied with IM requests ? since always they are occupying with a thread , it would be going above the limits of threads, I guess. So how can i find a solution for this matter ? Many Thanks Shaine -- View this message in context: http://www.nabble.com/After-some-time-url_redirect-program-hangs.-tp18396981p18396981.html Sent from the Squid - Users mailing list archive at Nabble.com.
