Hi all,

An hour ago my portal stopped working and upon signing into the server remotely I found it was using 100% CPU. I recycle the app pool for the portal and that seemed to sort it out.

I found a long string of errors in the log and am hoping that someone might be able to shed some light on it.

I have a file sync scheduled once a day and that is uaually fine but sometimes fails repeatedly. That's not a big issue and I think it being fixed in the next DNN release. Today it did that as well, but in addition had the following errors I've never seen before:

InnerException: The path is not of a legal form.
FileName:
FileLineNumber: -1
FileColumnNumber: -1
Method:
StackTrace:
Message: System.ArgumentException: The path is not of a legal form. at System.IO.Path.NormalizePathFast(String path, Boolean fullCheck) at System.IO.Path.GetFullPathInternal(String path) at System.IO.DirectoryInfo..ctor(String path) at DotNetNuke.Common.Utilities.FileSystemUtils.SynchronizeFolder(Int32 PortalId, String physicalPath, String relativePath, Boolean isRecursive, Boolean syncFiles, Boolean forceFolderSync) at DotNetNuke.Services.FileSystem.SynchronizeFileSystem.Synchronize() at DotNetNuke.Services.FileSystem.SynchronizeFileSystem.DoWork()

Lots of these:

InnerException: Object reference not set to an instance of an object.
FileName:
FileLineNumber: -1
FileColumnNumber: -1
Method:
StackTrace:
Message: System.NullReferenceException: Object reference not set to an instance of an object. at DotNetNuke.Services.FileSystem.FolderController.GetMappedDirectory(String VirtualDirectory)

Then a couple of these:

THREAD ID: 6

Folllowed by more of the first one above.

Perhaps somethign external caused this?

Thanks for any advice

Thanks for the pointer Sebastian. I'm not sure what qualifies as incorrect so I'll just see what the entries are in those tables.

I've been up and down the lists and it all looks pretty good. I can't see any funny characters or anything. I'll just keep watching and see what happens.

I must say I'm finding that DNN 4.7 is producing a lot more exceptions that 4.6.2 which was the cleanest version yet for me.
