Is this a CF webservice? -----Original Message----- From: cfaussie@googlegroups.com [mailto:cfaus...@googlegroups.com] On Behalf Of Matthew Sent: Tuesday, 6 January 2009 5:21 PM To: cfaussie Subject: [cfaussie] JRUN hanging
Hi everyone >From time to time our website appears to hand. I believe it is CF (or JRun) chocking because each time it happens I can still connect to the web server via FTP, RDP, DB access. When I look at the Task Manager jrun.exe is using max CPU. If I restart the CF service or End Process on jrun.exe everything recovers. I'm pretty sure I know which bit of code is causing the problem. It's a web service call to a 3rd party (used quite a lot by users on the website). Most of the time when the website hangs I can't browse to the 3rd party's web service. I've tried setting timeouts on the web service call by using CFINVOKE, CreateObject, CFOBJECT etc but no improvement. I need to allow for up to 60s because some of the calls are quite complex. I'm trying to work out why it's hanging. I suspect that because CF is allowing 8 simaltaneous requests and each gets 60 seconds then once all these slots are taken up everyone else goes on a queue and with all that load the server appears to hang because it's in constant use i.e. after 60 seconds user 1 gets his timeout so user 9 takes position 8 and round and round it goes and it never stops because with constant traffic taking up 8 request slots and all taking up resources for 60 seconds it appears to hang. Does this make sense? So the question is: how do I save the server from getting into this state. I'm thinking I need some sort of scheduled task which probes the web service every 10 seconds to work out if it's up. Perhaps if it times out (3 times just to be sure) I shut of the web service (which means the rest of the website is still up). The scheduled task keeps running until no timeout occurs and then it re-activates the web service for everyone else. Has anyone been through something like this before? How did you work around it?
