SP2013 Error - [Forced due to logging gap, Original Level: Verbose] GetUriScheme (...)

I found an issue with a clients SharePoint 2013 today and thought I'd share.

Symptoms

• High CPU on w3wp process
• Pages (including system pages) would not load and eventually error after a few minutes
• No obvious error message in logs

What I did find in the ULS logs was:

[Forced due to logging gap, Original Level: Verbose] GetUriScheme(/web/Pages/Apage.aspx)

Cause

Something in that page was keeping SharePoint busy.  I don't know what it was as it had been created by someone else.  It felt like an infinite loop error, but who knows....

Fix

Delete the file.  (Had to check in the file first).

Made some simple scripts to help.

• Dir-SPFile (Show files in a list)
• CheckIn-SPFile (Checks in the specified file)
• Del-SPFile (Deletes the file.  No confirmation required)

Dir-SPFile

#Script: Dir-SPFile
#Usage: .\Dir-SPFile.ps1 http://my2013site Pages
param (
$webUrl = $(throw "Please specify parameter webUrl"),
$listName = $(throw "Please specify parameter listName")
)
$web = Get-SPWeb $webUrl -Limit all
if($web -ne $null)
{
$web.Lists[$listName].Items | ft Id, Title, Url
}
else
{
throw 'Unable to locate site ' + $webUrl
}

CheckIn-SPFile

#Script: CheckIn-SPFile
#Usage: .\CheckIn-SPFile.ps1 http://my2013site /Pages/SomePage.aspx
param (
$webUrl = $(throw "Please specify parameter webUrl"),
$fileUrl = $(throw "Please specify parameter fileUrl")
)


$web = Get-SPWeb $webUrl -Limit all
if($web -ne $null)
{
$file = $web.GetFile($webUrl + $fileUrl)
if($file -eq $null -or !$file.Exists)
{
throw 'Unable to locate file ' + $webUrl + $fileUrl
}
if($file.CheckedOutBy -eq $null)
{
throw 'file ' + $webUrl + $fileUrl + " is already checked in"
}
$file.CheckIn('Forced Checkin');
"Complete - $webUrl $fileUrl Checked In"
}
else
{
throw 'Unable to locate site ' + $webUrl
}

Del-SPFile

#Script: Del-SPFile

#Usage: .\Del-SPFile.ps1 http://my2013site /Pages/SomePage.aspx

param (

$webUrl = $(throw "Please specify parameter webUrl"),

$fileUrl = $(throw "Please specify parameter fileUrl")

)

$web = Get-SPWeb $webUrl -Limit all

if($web -ne $null)

{

$file = $web.GetFile($webUrl + $fileUrl)

if($file -eq $null -or !$file.Exists)

{

throw 'Unable to locate file ' + $webUrl + $fileUrl

}

$file.Delete();

"Complete - $webUrl $fileUrl Deleted"

}

else

{

throw 'Unable to locate site ' + $webUrl

}
