Hi hemanth3005,

To investigate what is the cause of the crash capture a dump file that will contain detailed info what is causing this. Please try to follow following steps:
1. Have the site crash again
2. At the server open Windows Task manager and in the processes tab locate w3wp that is used to run the site
3. Right click w3wp and select "Create Dump file".

Once the dump file gets generated install Debug diag tool: https://www.microsoft.com/en-us/download/details.aspx?id=49924 and analyze the dump. The stack trace of the problem will be present and the failing functionality that causes the problem in clr.dll will be present there.
