So, we're having a issue where some of our longer running processes are crashing with a 503 IIS error of Server Unavailable. We have tried all the suggested settings of tuning the connectors using the "workers.properties" and "server.xml" files. We've rebuilt all the connectors after the most recent updates. I've even disabled IIS Rapid Fail. But the issue continues to happen.
We have CF11 Update 5, Win 2008 R2, IIS 7.
The crash usually occurs at around 60 seconds of a page load. All the timeout settings I can find I've set for 240 seconds or more yet we keep hitting this 60 second wall.
The only thing that looks to be a clue is in the ISAPI logs which seems to show the connector constantly restarting. Also, we suspect some of our processes are taking extra long to complete due to this known bug. I believe this is related to an issue Ben Nadel has also blogged about.
We've had huge processes in the past that took 4 to 5 minutes to complete without issue. But that was on CF 8, 9, 10. This is a relatively new install of CF11 and we need help.
What can we do to stop this connector from crashing!? ISAPI log below:
