CF using up all available bandwidth?!
Hello, I was wondering if anyone had experienced something like this before. We are connected to our CF 5 server by a 10 MB connection. The connection has tested out fine as far as all the techs are concerned. However, every once in a while all bandwidth will get choked up or bottlenecked to the point where no access of any kind is available (for up to 15 seconds). Then it will return to normal as if nothing happened. At first I was absolutely convinced it was a worm or virus, but now I'm not so sure. I have tried isolating each and every machine on the network and it doesn't seem to make a difference. The only thing that I can think of is that maybe CF is gobbling up all of the available bandwidth when multiple concurrent attempts are made to access the server and databases. Maybe I'm totally off base and it is not related to CF at all, but I'm reaching at this point trying to explain an event that is random and sporadic and unreproducible. Any thoughts or comments would be greatly appreciated.

If you running a Windows LAN watch out for the dreaded elections, which will saturate a 10MB link in no time. Even better they often appear to happen at random. -Matt On Wednesday, August 27, 2003, at 10:09 AM, Charles Nahm wrote: Hello, I was wondering if anyone had experienced something like this before.

If you're using WINS to resolve names, one of the machines on the network must be a 'master browser' and hold the up to date list of machines. Every so often (I think it's every 15 minutes) one of the other machines will decide it needs to check if the master is OK, and if not, start a process to 'elect' a new master. This causes a packet storm. On slow or congeted networks this can be a pain. I'd suggest setting up ethereal, tcpdump or something and looking at the network trafic directly. - Tom C Land of the free, home of the brave... you have to be brave to live there and enjoy the freedoms ~| Archives: http://www.houseoffusion.com/lists.cfm?link=t:4 Subscription: http://www.houseoffusion.com/lists.cfm?link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4 Get the mailserver that powers this list at http://www.coolfusion.com

Re: CF using up all available bandwidth?!
In Windows LANs you have what is called the master browser, which keeps tracks of other Windows machines on the network. This is the machine that is in fact polled for information when a user opens up network neighborhood and starts looking at machines and their associated shares and printers. In a properly setup Windows LAN, the master browser should be the PDC. However, if for whatever reason the PDC is not responding as the master browser than a new master browser must be elected. When election is happening every Windows machine is broadcasting to the entire LAN their capabilities to take over as a master browser. Sometimes a master browser is elected that can't really handle the responsibility so another election ensues. These can continue for some time until a proper master browser is found or the LAN administrator takes preventive measures. -Matt On Wednesday, August 27, 2003, at 10:23 AM, Charles Nahm wrote: Matt, We are running a Windows LAN, what exactly is a dreaded election?
