Admin: Crushes, critical failures

ААА, мир упал и не встаёт!

После краша или планового ребута мир будет пытаться подняться вновь каждую минуту. Логи всех таких попыток видны в /home/dreamland/runtime/var/log. Изучив последнее сообщение в самом свежем логе, можно понять причину, по которой мир не может стартовать, и попытаться исправить.

Частые причины

Не найден внум при загрузке дропов или профайлов

Логи:

[Dec 24 21:12:33]:N: Try ./var/db/oldstyle/player/bast.player, bast
[Dec 24 21:12:33]:E: Exception: get_obj_index: vnum 18167 not found on world startup

Исправление:

• Редактируем профайл игрока ./var/db/oldstyle/player/bast.player и вырезаем глючный предмет, от #O до слова End.
• Аналогично может заглючить и нуждаться в редактировании файл с мобами в комнате, ./var/db/saved/mobs/xxx/yyy.

Поломанный XML профайл у расы, класса, умения

Логи:

[Dec 26 19:20:03]:E: open tag != close tag male!=node:: : at line 313
[Dec 26 19:20:03]:N: unload [iomanager] so

Исправление:

• Имя заглючившего файла не видно, но по имени каталога (/home/dreamland/runtime/share/DL/professions), имени тэга male и номеру строки можно угадать что за файл и исправить поломанные теги.
