404 Service not found on first load

ShawnHolyoak — Wed, 28 Mar 2012 19:34:07 GMT

I keep having an intermittent bug where I get a 404 not found for my map services, but only on first load. So when I fire up my web application, one or more of my services doesn't load. Clicking reload in the browser always eliminates the error. It's not always the same service or services that can't be found, either. What might be going on, and how can I fix this? Thanks.

Can you provide a link to your app or a sample that reproduces the issue?

The app is not on a publicly available server, but I've attached a zip file with all the code for the website. I can't be sure whether that will reproduce the issue, but it's the best I can do at this point.

Can you provide a link to your app or a sample that reproduces the issue?

Any thoughts on this? It's only from one server; would it be a network, or other hardware, issue?

Sorry you havent gotten much response, periodic/occasional bugs like this are the hardest to track down.

My guess is that you may be capping out your maximum instances on your services. Have you looked at the number of running instances versus the maximum instances in arccatalog when you hit the web service?

I would try upping the number of maximum instances and seeing if the problem improves.
