    This still happens on CF10 update 15 (1.2.40 connector). For us, someone posts a massive POST command to the server, then there is an error 500 in the logs. Tuning does nothing to solve this issue. The only consolation is that the server does not crash, but there is no way to stop the error from occurring still. Even if we detect POST data and stop it in in CFML code, the error still persists. I reckon that a user could take a site offline with repeated POSTs of this nature.

    We are having similar issues, though the problem doesn't seem to have any relation to load. I'm implementing the changes outlined here:

    Will report back if this seems to help. We are averaging at least one crash per day. Sometimes it will be fine for several days, then it will go down multiple times in a 24 hour period.

    We are running the same exact configuration as noted above except we have 16 GB of RAM on a virtual server. We upgraded to ColdFusion 10 because our our last web server (ColdFusion 9) was compromised. I installed all Windows updates and have CF 10 up to Update 11. The problem is frustrating because the only way I know how to resolve it it to restart the IIS Service. Hopefully this will be addressed soon as I am losing too much sleep over this issue.

    **** Please check the comment below by Vishal Jaswal *****
    You need to tune the server to address this. We have worked with quite a few customers and confirmed that tuning the server as per the following blog entry actually resolves the problem.

    The same blog entry should be applicable for Apache as well.
    Does this not resolve your problem?

    This was happening to us apparently with large number of website hits, but not anymore. NOW it happens when PCI scans our servers for compliance. It was happening every month, now about every other month. It just happened this morning on 4/23/13, so the bug hasn't been entirely fixed.

  • etnevels1

    8:52:52 AM GMT+00:00 Feb 19, 2013

    Exact server here. Only have this with CF10 - have installed all updates. What I notice is this only happens on sites that have several bad page requests. For example if the client is new to us and has some links out there to non-existent pages, then that site will crash several times a day after a few of these bad GET page requests are made. Here is a recent log entry that killed the site: 2013-02-19 16:06:41 W3SVC26 FULLPARTNER5 GET /wp-login.php - Mozilla/5.0+(Windows;+U;+Windows+NT+5.1;+en-US;+rv: - - 200 0 235 93
    Notice the page is /wp-login.php,obviously a page from the previous site that does not exist on the new site.
    We have only used CF10 for about 3 weeks. No such problem in CF9 or CF8 on these exact same sites. Clearly a CF10 issue, clearly a jakarta issue. I shudder to think what will happen when the PCI guys hit a site for a vulnerability scan - the always try to hit a hundred bad pages to see what the server does. Probably the server will crash! So far we have not had a PCI scan on this server....

  • *** Tyson ***

    7:06:07 AM GMT+00:00 Oct 31, 2012

    Same exact issue for me with one of my biggest clients. Constant crashes on our ColdFusion 10 server multiple times per day. Event viewer is riddled with constant errors (thousands per day) from the w3wp.exe service and the ISAPI connector. I was able to seemingly relieve the situation somewhat by disabling IIS 7.5's "Rapid-Fail Protection" on the application pools (which I can't imagine is advisable for a production environment), but that only seems to have decreased the frequency of the crashes slightly - from a dozen times each day, down to only a few times per day. Completely unacceptable.

    It absolutely astounds me that Adobe has not halted in their tracks and prioritized every single reputatble development resource with developing and releasing an effective resolution to this problem. Honestly, it gives me cause (for the first time in 17 years of ColdFusion development and support) to consider migrating away from ColdFusion to a different platform. Updater 3 was apparently a disaster (thank God I checked for community feedback before installing it), but I've not heard a single follow up about the fix to this problem since the Updater 3 was recalled by Adobe - and that was a couple weeks ago.

    How on earth can an absolutely critical bug like this remain open and unaddressed for so long without any resolution!? Adobe, you've -completely- dropped the ball on this and disappointed droves upon droves of loyal customers, developers, and community members. Our clients are angry. Not only are they losing money and credibility every single day that this bug remains unfixed, but their confidence and support of ColdFusion as a platform is dwindling. What in the world is holding up the completion and release of a prioritized hot fix for this issue!? Forget about bundling it up with a bunch of other fixes at this point. This bug is critical enough to stand on its own and be addressed immediately!


  • *** Tyson ***

    6:32:02 AM GMT+00:00 Oct 31, 2012

    I don't understand -WHY- this issue hasn't been fixed yet. It's bringing down my Fortune 200 client's server multiple times per day. Can Adobe AT LEAST provide an ETA on a fix for these connector issues!?

  • Gerard McBreen

    The error messages I see are identical to those shown in this bug fix. Can't discern exactly what users were doing at the time, but only resolution was to restart CF service.

    PLEASE fix this, as it is causing real issues on our production server. Our customers are VERY angry.

    We also need some information on server setup.
    1. How many sites in the IIS are configured with CF
    2. Have you tried giving the timeout value in wsconfig->advanced option.
    3. Enable the cachewebserverpath option in the server admin settings page and verify if you can repro the issue.
    4. Give us server load information about number of request at normal and peak time.

CF10 64-bit on Win2008with 24 gb ram. The reputation of ColdFusion is on the line in this 6+ enterprise server licensed organization.

    I am having the exact same problems despite performing all the suggested connector tuning. I have the latest CF10 Update 11 running, clean install, medium sized site, and yet continue to see 503 error messages a few times a week. Windows 2008 R2 (VMware), IIS 7.5. Never, ever had these problems with CF9 on 32-bit Windows 2003/IIS6. Thinking about falling back to CF9 but would really prefer for CF10 to work given all the time and $$$ spent. Will try to get in touch with Adobe privately, something I've never had to do in 16 years of working with CF. Bummer.

    We were live on Coldfusion 10 Standard Edition on 2 Windows Server 2008 VM (32 bit) for almost a week. Last night, both servers stopped responding at the same time. When a server was restarted, it would run ok initially on restart but then would lock up within the next 10 minutes. IIS logs show increased traffic from bots during that time. We had to revert back to Coldfusion 9.
