Re: JRun Throwing 503 Errors
In a nutshell, cfhttp calls hanging, stacking on top of each other, and eating up the JVM. ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;207172674;29440083;f Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:320746 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4
Re: JRun Throwing 503 Errors
I forgot to answer the last part of your question. The solution: I moved all of the cfhttp calls to their own server instance. ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;207172674;29440083;f Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:320747 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
RE: JRun Throwing 503 Errors
Yeah thought that would be the case. So, are they just slow running or was the end server not responding and causing them to stack? Did changing the concurrent requests setting the Admin help at all? Or just prolong the problem? I'd probably recommend using the timeout on cfhttp be set to solve this issue, at the moment it just sits indefinitely. Value, in seconds, that is the maximum time the request can take. If the time-out passes without a response, ColdFusion considers the request to have failed. If the client specifies a time-out in the URL search parameter (for example, ?RequestTime=120) ColdFusion uses the lesser of the URL time-out and the timeout attribute value; this ensures that the request times out before, or at the same time as, the page. If the URL does not specify a time-out, ColdFusion uses the lesser of the Administrator time-out and the timeout attribute value. If the time-out is not set in any of these, ColdFusion waits indefinitely for the cfhttp request to process. That won't solve the problem if they're just slow to return a large set of data however it'll solve the problem if you've got requests that are not responding.

Re: JRun Throwing 503 Errors
Suddenly our CF server is doing the same thing - off the charts with 503 errors from JRun - did you happen to ever figure out any sort of culprit or solution? Thanks K. No, I do not have monitoring turned on in production. As a matter of fact, until you just mentioned it, I completely forgot it even existed. ;-) (Which means that I don't know the answer to your questions, but I shall check it out.) ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;207172674;29440083;f Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:320737 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
Re: JRun Throwing 503 Errors
Hmm... It just happened again. Now here's the strange part: All of my sites return 503 timeout errors, yet I can still move about the CFAdmin just like normal. WTF? I have no idea what the deal is. ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;207172674;29440083;f Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:320621 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
RE: JRun Throwing 503 Errors
Matt, Hope you're well mate. With regards to this it looks as if requests are timing out whilst sat in the request pool before being processed. My guess would be that this might be related to those scheduled tasks, if they're running and consuming all available requests due to the slow running speed and creating a bottleneck then you'll be quing other requests for too long and causing them to time out. Try bumping the number if simultaneous requests up and see if that solves the problem, if it does then I'd look at making those scheduled tasks more efficient. Rob -Original Message- From: Matt Quackenbush [mailto:quackfu...@gmail.com] Sent: 18 March 2009 10:31 To: cf-talk Subject: JRun Throwing 503 Errors Hello, On one of my servers, starting about 12 hours ago, all of a sudden JRun seems to be shutting down or something. It quits responding and displays the following error message on every request: 503 Request timed out waiting to execute For the last 12 hours this has occurred repeatedly, with a max interval of 3 hours. Nothing in the CF logs gives me any indication of what the cause is. Where can I check to try and pinpoint the cause? The server specs: CPU: 2x Dual-Core Xeon RAM: 4GB ECC Registered OS: Windows Server 2003 CF:CF8 Enterprise, JRun configuration Web: IIS DB:None The only thing that I can think of is the fact that there are a lot of long-running scheduled tasks that rely on cfhttp calls. Could it be possible that cfhttp is timing out and causing JRun to shut down? That really doesn't seem to make a lot of sense to me, but I can think of no other reason. Nothing else is affected, only JRun. Any thoughts, tips, or suggestions would be greatly appreciated.
