    Hi,

    our site is loadbalanced between two servers, so the physical path of the site is on a networkdrive. Since one month we had trouble with our site, sporadically the servers did not response to http, so an error page appears. Today we took a look in the application logs of the server and there where lots of Errors like this:

    TransmitFile failed. File Name: \\networkdrive\Websites\Site\Portals\0\DreamSlider\1078\Cache\26D7E0A896FB8F5FFD3B15A3AF5EAAB02D76502F.tmp, HRESULT: 0x80070002

    and lots of other errors like this:

    Faulting application name: w3wp.exe, version: 7.5.7601.17514, time stamp: 0x4ce7afa2
    Faulting module name: KERNELBASE.dll, version: 6.1.7601.17651, time stamp: 0x4e21213c
    Exception code: 0xe0434f4d
    Fault offset: 0x000000000000cacd

    Report Id: a6873d49-1acc-11e1-ac7e-0050568300ab

    ---------------------------------------------------------------------------------------------------------------------------------------
    and

    An unhandled exception occurred and the process was terminated.

    Application ID: /LM/W3SVC/2/ROOT

    Process ID: 2488

    Exception: System.Web.HttpException

    Message: An error occurred while communicating with the remote host. The error code is 0x80070006.

    InnerException: System.Runtime.InteropServices.COMException

    Message: The handle is invalid. (Exception from HRESULT: 0x80070006 (E_HANDLE))

    StackTrace: 

    ----------------------------------------------------------------------------------------------------------------------------------------

    These errors occured exactly at the same time, as we see the error page instead of our site.
    I disabled the Server Cache option in all the slider Module instances on our site, and the site runs stable now and there are no more errors.

    Can you please try to check this out? I think the problem is the network drive, because as we switched the site to a local folder on the servers these errors dissapeared.

    Regards
    Sabine

    Ah, so THAT's why the site was slowing to a crawl when I was working in some new Deeamslider pabels yesterday. I had a sneaking suspicion about Dreamslider being the culprit.

    In my case, happening on every portal that has Dreamslider installed. No server farms in use. Here is a sample from the App log - always travel in packs of 3 for this issue, and are presented in order of occurrance.

    #1 Error:
    TransmitFile failed. File Name: C:\inetpub\DotNetNuke\HNS-11\Portals\1\DreamSlider\2283\Cache\A7CBB5D8F01F753BC5FDF44B9B1849FCE52FFC45.tmp, HRESULT: 0x80070002

    #2 Error:
    An unhandled exception occurred and the process was terminated.
    Application ID: /LM/W3SVC/46/ROOT
    Process ID: 13356
    Exception: System.Web.HttpException
    Message: An error occurred while communicating with the remote host. The error code is 0x80070006.

    InnerException: System.Runtime.InteropServices.COMException

    I want to thank all of you that accompany us since 2008. The time when we introduced number one slider for DotNetNuke. and now that we've tried to be best.
    Despite the good features Dream Slider has, there are some missing features in our module that we are aware of them. So we started rewriting a new slider engine, this time based on jQuery from 2 months ago. The engine is ready right now and are going to put it in DotNetNuke module.
    We kindly ask you to continue being with us to create new version of our module.  New version has some interesting features as below:

    - Responsive Slider
    - Support for iOS and android devices
    - Touch gestures navigation for iOS, Android and other touch devices
    - Multiple & unlimited transitions
    - Define Transition per Slide
    - Different location and size for introtext
