Problem: Service Unavailable, HTTP Error 503
Reason: IIS Application Pool stopped
This issue appears after 5 SAP login request and depends from Application Pool "Rapid-Fail Protection".
The "Maximum Failures" is 5 (default) . If the "Rapid-Fail Protection" is disabled, no HTTP Error 503 appears.
But this don't averts the crashes at a new SAP Login.
The Application Event Log contains a crash record for each SAP Login. For each crash are dump files written.
IIS starts after a abnormal program end a new Worker Process for the SAP Session.
Is this behavior okay or can we avoid the crashes ?
Notes:
SAPConsole 7.30 , 64Bit installed on a VM with Windows 2008 R2.
The login request runs with command line parameters for a automatic login.
The SAPConsole is using a "No Managed" Application Pool and is tested with Pipline Mode Classic and Integrated.
