I have two servers that are behind the loader in my service tier. Both of them must be identical - IIS configures the same thing, AppFabric (to keep the two services overclocked), application pools running either with a service account or with an application pool identifier. Everything works on one server. On another server, my three application pools (the two that AppFabric overclocks under service accounts, and the one that is just a standard application pool without changes made by default) stop working almost immediately as soon as I start them (sometimes upon first request).
I get five of the following errors in the application log every time I try to start one of the application pools:
An error occurred while processing the autostart of the managed application service in the configuration path: "MACHINE / WEBROOT / APPHOST / Site / App". Error message returned: ''. The workflow will be marked unhealthy and will be disabled. The data field contains an error code.
The specified error code 80070005.
This is actually for the same site / application regardless of the launch of the application pool (although it may change after the application pools are recreated).
In syslog, I get the following warning five times before errors ( Application pool 'AppPool' is being automatically disabled due to a series of failures in the process(es) serving that application pool.):
