RE: How to stop an infinite CF loop?
We didn't shut the service down right away because what it was doing was mild and our live system had people logged in and was running counts and orders. We has access to the code. We tried forcing the template to error out, but the system had cached it and was ignoring all the updates we were making. We checked for scheduling. We're just looking for a way to deal with situations like this from a remote location. We've been considering the custom tag that allows control of services. I was hoping there was another way other than shutting down the service. Lon Lentz Applications Developer - GetLists.Com DataWarehousing and List Sales - Market your lists on the Net!

I can't believe you didn't immediately shut down the CF server if you suspected there was a template running amok. I'm aware of only two things that would cause a working template to terminate prematurely. The first is if the request timeout is met. You have a default template timeout set for the CF server in the Administrator, but if the template were called with ?RequestTimeout=xx, it is overridden. Trouble with this is that anyone can alter the request timeout by simply putting that url parameter in the request. The other would be to kill the CF application server. There might have been some other things you could have done to either cause an error or alleviate the problem. If you knew what the rogue template was doing, and had access to the code you could do this. You might have shut down the email server, for example. None of those would have been nearly as effective as simply shutting down CF server. One thing you'd need to watch out for would be whether the template had scheduled itself using CFSCHEDULE to start up again at a later time. -- Archives: http://www.eGroups.com/list/cf-talk To Unsubscribe visit http://www.houseoffusion.com/index.cfm?sidebar=listsbody=lists/cf_talk or send a message to [EMAIL PROTECTED] with 'unsubscribe' in the body.
RE: How to stop an infinite CF loop?
I agree. But there are times when everyone writes something that ends up doing the unexpected. And all he did was name the custom tag the same as the template calling it...

Re: How to stop an infinite CF loop?
hi, I seemed to have had the same problem with CF where according to some people say that the code runs into an infinite loop. And that is not possible cause i triple checked the code. Only here the code apparently queries SQL over and over a period of time the server crashes because it runs out of memory ! If it receives more than 200 active connections at a time ... it goes kaput !: ) I cant seem to isolate the problem to a specific page ...Atleast then I would know where the error is happening. regards vince At 09:33 AM 6/12/00 -0400, Lon Lentz wrote: I had posted this question, in a slightly more vague way, a couple weeks ago.

RE: How to stop an infinite CF loop?
Restart unresponsive server tracks unresponsive threads, and will restart the service if there are a certain number of unresponsive threads. If you have this set to 5, you would need 5 infinite loops before this would kick in. Timeout requests would limit the damage from an infinite loop.

Re: How to stop an infinite CF loop?
I think that's a given. But I think what he was wanting to know is ... once you discover an infinite loop is running, what can you do to stop it other than restart the server? Which seems like a sound thing to want to know. It would be pretty obvious that if you don't discover an infinite loop while you're writing the routine, the next most likely time to discover it is when it runs. What then?

That's not such a simple question. How is the CF server supposed to differentiate between a finite loop and an infinite loop? Is 1000 iterations too many? 10,000? 100,000? I'm sure there are valid processes that could loop that many times and still have a definite exit point. The only way for CF to tell what loops are infinite would be to examine the loop logic and decide if the exit state would ever be met. Considering that this could be incredibly difficult (or impossible) for even marginally complex loops I don't see how this could be efficiently included in the CF engine. The best solution is to hire programmers that don't write infinite loops g.
