Answer 1

i believe this issue may cause because of Orphan site content in content database, please run below script to check the orphan content in farm
if ( (Get-PSSnapin -Name Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue) -eq $null )
 {Add-PSSnapin Microsoft.SharePoint.Powershell}
 set-location "C:\Program Files\Common Files\Microsoft Shared\web server extensions\14\BIN"
 $SPFarm = Get-SPFarm
 $contentWebAppServices = (Get-SPFarm).services | ? {$_.typename -eq "Microsoft SharePoint Foundation Web Application"}
 foreach ($SPWebApp in $contentWebAppServices.WebApplications)
 foreach ($SPSite in $SPWebApp.Sites)
 Write-Host "Going thru Site Collection" $SPSite.Url
 $SPSite.Url >> C:\SPSiteOrphanObject.txt
 stsadm.exe -o databaserepair -url $SPSite.Url -databasename $SPSite.ContentDatabase.Name >> C:\SPSiteOrphanObject.txt
 $SPSite.Dispose()
Note: it will create the orphan content details in C:\SPSiteOrphanObject.txt
