Не компилируется java файлы

[AndreyP]

Готовлюсь к олимпиаде. Установил Ejudge 2.3.24 и ядро 3.4.10+patch.
При отправке java файла получаю следующее сообщение:

Code: Select all

"javac" -source 1.6 -Xlint:unchecked  a_4.java
Error occurred during initialization of VM

Подскажите, как решить проблему.
При попытке скомпилировать в ручную получаю:

Code: Select all

если это 64-битная система, попробуйте увеличить compile_max_vm_size

Code: Select all

compile_max_vm_size = 1G

[AndreyP]

Спасибо, проблема разрешилась.
Но почему нужно так много памяти для javac? На сервере всего 1G.

[cher]

Ставить на 1GB памяти 64-битную систему - это не очень удачное решение.

[AndreyP]

Система Ubuntu стоит как клиент для Hyper-V x64, а на момент проведения олимпиады поднимаю до 3G. А для судентов она работает с 1G.

[sergpet]

Кстати, обнаружил интересную ситуацию, если ставить

compile_max_vm_size более 1 G то Check contests settings пишет error.

Поставил 1G, отправил в систему 40 посылок на яве, и сделал реджадж, получилось так что часть посылок оттестировалось нормально, а часть дало Сompile error со следующей ошибкой.
