[JSP] CompilationException JVM 메모리 문제

개발서버에서 갑자기 JSP 컴파일 이 안된다............ 멘붕.......

"Not enough space" 디스크 용량 체크해 봤지만 그 문제는 아니였다....

고민 후 혹시...JVM ???? 메모리 부족인가 싶어 검색도 좀 해보니 이런저런 뚜렷한 답을 얻지 못했지만

장비램이 2기가인데 was서버가 5개에 JVM 메모리가 512로 잡혀 있어서 메모리 부족으로 컴파일이 안됨
메모리가 부족해서 다른 was 서버 jvm 을 줄여서 해결함

 

※ 맥시멈 512로 잡아둬도 그만큼 할당하는것 같지는 않음.. 이 부분에 대한 지식이 아직 부족함..

    ServletContext 는 "*" 처리함.
