| Description | User Mode Process Dump service was started successfully. |
| Event Information | According to Microsoft: CAUSE: This problem occurs because the User Mode Process dump can only be configured to dump a process on first chance exceptions. These dumps are being generated because of first chance "access violations" that are handled by the performance counters, which do not cause IIS to crash. However, because the User Mode Process dump cannot be configured to ignore these first chance exceptions (or first chance exceptions of any kind), it generates a dump file. RESOLUTION: There are two workarounds for this issue: 1. Do not run performance monitor against the IIS server remotely while the User Mode Process dump is being used. 2. Use the IIS Exception Monitor and the Script file customization wizard to configure the IIS Exception Monitor to ignore first chance access violations. |
