I am using the BitNami Redmine stack 2.0.1 on Windows Server 2008 and around every two to three hours, Redmine will return a "503 service temporarily unavailable error" when trying to access it. The only way to restore Redmine is to restart the redmineThin1 and redmineThin2 services.
If I try to access Redmine while it's down, these errors appear in \BitNami Redmine Stack\apache2\logs\error.log
[Thu Jun 07 12:10:35 2012] [error] (OS 10061)No connection could be made because the target machine actively refused it. : proxy: HTTP: attempt to connect to 127.0.0.1:3001 (127.0.0.1) failed
[Thu Jun 07 12:10:35 2012] [error] ap_proxy_connect_backend disabling worker for (127.0.0.1)
It appears that ports 3001 and 3002 correspond to the redmineThin1 and redmineThin2 services. If one service isn't restarted, then it will continue to throw this error even if Redmine is accessible. The Redmine production.log doesn't show anything about this and reconnect is set to true in the database.yml file.
Does anyone know how I can stop these services from failing or locking up? Also, does anyone know what the log files for the redmineThin services are located? Any help with this would be greatly appreciated.
