javac memory error

vyahhi · Post by **vyahhi** » 15 September 2011, 15:08

Решения, посланные на Java получают "Compilation error":

"javac" -source 1.6 -Xlint:unchecked  Main.java
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.

При этом на машине (Ubuntu, 2.6.32-5-xen-amd64):

Code: Select all

Mem:   7333724k total,  5158860k used,  2174864k free,  1005852k buffers
Swap: 10485752k total,    61656k used, 10424096k free,  3641192k cached

С остальными языками (С++, Python) всё ОК.

Не подскажите, в чём может быть проблема?

P.S. Если сделать с тем же кодом

Code: Select all

javac -source 1.6 -Xlint:unchecked  Main.java

в консоли, то всё хорошо компилируется.

Изменение

Code: Select all

compile_max_vm_size = 256M

на

Code: Select all

compile_max_vm_size = 512M

в /home/judges/000003/conf/serve.cfg + ejudge-control stop + ejudge-control start + Restart management не помогло

попробуйте исправить в /home/judges/compile/conf/compile.cfg

vyahhi · Post by **vyahhi** » 19 September 2011, 17:42

Добавил туда строку (её вообще не было):

Code: Select all

compile_max_vm_size = 512M

Не помогло.

Кстати, этот файл (/home/judges/compile/conf/compile.cfg) же

Code: Select all

# Generated by ejudge-configure-compilers, version 2.3.19+ (SVN r6401)
# Generation date: 2011/09/17 13:30:36

Всё равно перетёрся бы при следующем запуске ejudge-configure-compilers?

Может поставить размер 1G?

Всё не помогло

А возможно ли куда-то ручками прописать опции для javac (например compile/conf/lang.d/javac.cfg?). Откуда он вызывается и берёт "-source 1.6 -Xlint:unchecked"?

Post by **cher** » 21 September 2011, 11:31

Смотрите в /home/judges/compile/scripts/javac и в исходниках файл extra/ej-javac.c

Но мне кажется, что где-то у вас с конфигурацией напутано.

vyahhi · Post by **vyahhi** » 21 September 2011, 11:56

Мне тоже кажется, что проблема в конфигах, но никак не пойму, что не так... Кстати, если прописать ручками в /home/judges/compile/scripts/javac флаг -J-Xmx512M, то уже падает не javac от недостатка памяти, а jar

Code: Select all

"javac" -source 1.6 -J-Xmx512M -Xlint:unchecked  Main.java
"/usr/bin/jar" cvfm "000024.jar" Main.mf *.class
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.

А можете выложить или прислать конфигурационные файлы serve.cfg турнира и compile.cfg?

Все выглядит нормально.

Можно попробовать в скрипт javac вставить печать лимитов:
bash -c 'ulimit -a'
посмотреть, что выводится
