503 Error exporting a huge application

Error

The System Has Encountered an Error

HTTP Code: 503 The system has encountered an error. Please try again later.

Any idea how to fix this ? Please note that this is export not import . It seems the process is hanging at inspect stage ? Anyway to skip inspect or increase the timeout . problem is that unlike import there is no way to attach a property file ? I don't think export is happening at the background as tomcat log file has no mention of export.
