AppEngine JRuby - OutOfMemoryError : Java 힙 공간 - 해결할 수 있습니까?

Question

AppEngine JRuby on Rails (SDK 버전 1.3.3.1)를 사용합니다. 자주 발생하는 문제는 서버가 실제로 느리게 진행되어서 서버가 종료되어 OutOfMemoryError가 터미널 (OSX)에 전달 될 때까지 발생합니다.

요청 자체는 매우 가벼워서 DataMapper를 사용하여 엔티티를 찾거나 저장하는 것이 아닙니다.

appspot에서이 문제는 발생하지 않습니다.

JRuby의 힙 공간을 확장하는 방법이 있습니까?
