My vb.net web service method will hang/stop processing after about 1 minute or so. Usually happens while in the middle of a long loop through a table. It doesn't return any sort of message to the calling client until everything just times out. I've built a log into my application so I can see what is happening inside...it always seems to end in a slightly different place every time, depending on the number of simultaneous requests on the machine.
Of course it works fine on my development machine - the problems only occur on the production side.
I have my IIS timeout set to 600 seconds, so I don't think the problem occurs there.
I know this seems like a strange question...any ideas as to what could be the culprit? Is there a config file I can alter? A log I can look at?
