Can you place the entire stacktrace of the error here. Will give some more information.

Any ideas please about this error?

Thank you.

Do you use this code in your own views ?

Dave

No, I am not using the umbraco.library and not even the method .GetXmlNodeCurrent.

Hi,

I have now deployed to a server... and there such error ocurring:

1. First, when trying to access the Developers section in the hosted website, the Message "Server error: Contact administrator, see log for full details. Failed to retrieve indexer details". The same details as mentioned above are there in the log file.

This is the error in detail from the NEtwork tab from dev-tools:

    exceptionMessage: "The 'ObjectContent`1' type failed to serialize the response body for content type 'application/json; charset=utf-8'."
    exceptionType: "System.InvalidOperationException"
    innerException: {message: "An error has occurred.", exceptionMessage: "Array dimensions exceeded supported range.",…}
    message: "An error has occurred."
    stackTrace: null

Also, only in the deployed Site, where I have nuPickers using Lucene, this error is occuring:

ExceptionMessage: "Array dimensions exceeded supported range."
ExceptionType: "System.OutOfMemoryException"
Message: "An error has occurred."
StackTrace: " at Lucene.Net.Index.SegmentInfo..ctor(Directory dir, Int32 format, IndexInput input)

Any help is much appreciated.

Thank you.

Related to the error above, as explained here:

Exceptions are expensive when it comes to memory. When an exception is thrown, not only does the GC allocate memory for the exception itself, the message of the exception (a string), and the stack trace, but also memory needed to store any inner exceptions and the corresponding objects associated with that exception. If your application is throwing a lot of exceptions, you can end up with a high memory situation quite easily.

these exceptions are causing problems to memory on the hosted server.

Have somebody has any idea why this error is being thrown: Could not retrieve current xml node

System.NullReferenceException: Object reference not set to an instance of an object.

   at umbraco.library.GetXmlNodeCurrent()

Any help please?

Kind Regards

is working on a reply...
