Исключение нехватки памяти в WAS 6.1 и EJB 2.1
Моему приложению не хватает памяти и некоторое время получала внутреннюю ошибку сервера, после чего оно автоматически восстанавливалось и приложение работало нормально.
Мое приложение размещено на WAS 6.1 и использует Struts 1.1 и EJB 2.1. Вот журналы сервера приложений для ошибки. Не могли бы вы помочь мне в этом вопросе, пожалуйста.

java.lang.OutOfMemoryError предполагает, что вам не хватает памяти на сервере приложений. Для быстрого решения проблемы вы можете увеличить максимальный размер кучи на сервере приложений, но в целом вы должны включить многословный gc и генерировать дампы кучи. Затем проанализируйте дамп на предмет утечек памяти и выясните, что занимает место в куче.
Вы можете использовать инструменты из IBM Support Assistant (доступны бесплатно):
- Сборщик мусора и визуализатор памяти
- IBM HeapAnalyzer
