ZipSysAd870 Posted January 28, 2008 Share Posted January 28, 2008 Hello,I am having an issue with using server 2003 as a web server. At this point, I have a a blade web server that receives thousands of web calls a day from devices that access a site to upload data to my system. This is TECHNICALLY on load balancing, however the other server has been down and needs repair, but even when it was active, this issue occured. What is happening: we are losing devices. they get TCP timeout errors when trying to connect to the website. What I have done: replaced firewall/router (cisco ASA), tried to replicate the problem on a 2000 cluster that is still active elsewhere in the company (problem did not occur there, but this site will be shut down shortly), researched like you wouldn't believe on the internet. took one of my 2000 servers and placed in the same location as my 2003 cluster(could not duplicate problem), contacted my isp (was told my traffic was not curtailed port 80 and that they were not blocking anything coming into my router), verified that the devices in the field reporting into us were completely functional.What I am running: Windows server 2003 on a dell blade server with load balancing using cold fusion mx 7.I am wondering if anything has any ideas, I'm at a dead end.....-- Thanks for replying~ZSA"I may as well have a 24 hundred dollar deck of cards cause all I do on that thing is play solitare"~Larry the Cable Guy Link to comment Share on other sites More sharing options...
cluberti Posted January 28, 2008 Share Posted January 28, 2008 Do you have a network trace of this behavior, showing the connect and the timeout to one of the devices? The network stack in 2003 was far different than 2000, so we'd need to see the actual conversation failure to be sure. However, are you sure you aren't running out of something like ephemeral ports, or perhaps seeing kernel pool issues?How is the server configured (RAM-wise, boot.ini, etc)?

touchstone_81 Posted January 29, 2008 Share Posted January 29, 2008 Hmm if you are running IIS maybe you could check for any security tools like the IIS lockdown tool.By the way when you say-- Quote: "I am wondering if anything has any ideas, I'm at a dead end....." i am hoping that it was a typo.

adamt Posted January 31, 2008 Share Posted January 31, 2008 ColdFusion... ARGH!Are you using CF's own jrun HTTPd , or is it being run via IIS?Try running netstat -b and see if something/anything is actually listening on port 80.Can you do a telnet localhost 80and then send it:GET / HTTP/1.0- and get a response? NB - you probably won't be able to see what you're typing, and you need two carriage returns after the GET line.I tend to find CF issues with timeouts are usually down to bad CFML scripts, or broken dependencies like database backends.
