Analyze and Respond to CLR Crashes

When a CLR crashes, the .NET Machine Agent raises an event in the Controller. The events page on the application dashboard displays the number of server crash events, including CLR crashes, during the selected time range.
  1. Click the Server Crashes link in the application dashboard to display a list of all server crash events during the selected time range.
  2. Optional: Filter on the CLR Crash event type.
    Entries for individual CLR crashes display information about the crash event, including the process ID and the Windows event log ID.
    Note: After a CLR crash, IIS automatically tries to restart the CLR, so one issue frequently causes multiple CLR crash events.
  3. Double-click a CLR Crash type event to display more information in the CLR Crash panel:

    • The Summary tab shows the Windows process ID of the w3wp process that crashed and the Windows event log ID for the crash. The summary also includes the affected tier and node names.

      Note: If multiple tiers have nodes on the same machine, you may see more than one tier in the CLR Crash window.
    • The Details tab displays essential information about the crash.
    • The Actions Executed tab shows any actions the event triggers. See Monitor for CLR crash events.
    • Read and add new comments on the Comments tab. For example, you can add a comment to the CLR crash event to notify colleagues that of the issue.
