Grails on Google App Engine - Production Issue: Response 500 Error

I am using Grails (app-engine and gorm-jpa plugins) for the development.

I don't know why, But my application is running fine on local environment. But on Google App Engine, I am in-consistently (1 in 3 times) getting Error Code-500.

Also, in GAE logs - reason of request failure is its taking so long to execute the request (开发者_如何转开发usually more than 30 seconds).

Have anyone worked around the same kind of problem?

Have faced the same problem. Apparently grails startup and initialization take sufficiently long to exceed the deadline limit enforced by the app engine. See http://jira.codehaus.org/browse/GRAILSPLUGINS-1736

It was frustrating enough to have me migrate my app to Gaelyk - tough luck cause i really like grails
