  • intermittent 500 errors

    Jun 26, 2015 01:24 PM|jccondor|LINK

    We are experiencing intermittent 500.0 errors, around 10K out of 2Million (page hits).

    Windows Server 2008 R2 x64, IIS 7.5

    Logging at IIS at logs we have noticed that this problem is much larger than what we thought was happening. They appear all over the place The appear on static files as well as on the application (php files). They are also spread out during the day, with peaks when I have most activity. The server also run several sites, but all of them have the same type of issues.

    We have setup failed request logging and really can't make out what might be the cause.

    Any help highly appreciated.
