We had a custom webpart deployed in the SharePoint page. Faced this issue when loading the page and same was working before.

Error found in Event log:

System.StackOverflowException: Operation caused a stack overflow.

Reason:

This issue occurs when the query took longer than one 1 second to complete as normally XsltTransformTimeOut set to 1 in SP2013 farm.

To get your Timeout interval:

PS U:\> $farm=Get-SPFarm
PS U:\> $farm.XsltTransformTimeOut

we got value returned as 1

Increase timeout interval to fix this issue:

PS U:\> $farm=Get-SPFarm
PS U:\> $farm.XsltTransformTimeOut=20
PS U:\> $farm.update

You can also update to 5 and monitor for few days, if it is observed to be fine, then you can have 5 seconds as interval



$farm=Get-SPFarm
$farm.XsltTransformTimeOut=5
$farm.update
