.....
Mar 24 05:24:48 server kernel: [25268.532496] mlnet[2866]: segfault at 85e2324 ip 08289e5d sp bf841c50 error 4 in mlnet[8048000+2ec000]

Сколько файлов шарится? Грепните лог mldonkey по overflow - есть какие-то сообщения? После крэша покажите ещё вывод x/1000a $esp в gdb. Покажите вывод ulimit -s в консоли. Баг остаётся если отключить magic (определение типов файлов по содержимому - где-то в настройках должно быть)? _________________ Download \| Report bugs \| git mirror

1. Файлов шарится 2758.
2. В логе (со всеми включенными опциями) про overflow ничего не нашёл.
3. ulimit -s 8192
4. x/1000a $esp (сразу после "Backtrace stopped: previous frame...") выдаёт:

Но сегфолт в этот момент не происходит - если выйти из gdb процесс продолжает крутиться... Может я как-то неправильно Ваши указания по диагностике выполняю?
5. Насчёт magic - пересоберу с отключенным - отпишусь...

Аргх, ну да - неправильно :) (про magic отбой тогда). Запустите под gdb - дождитесь когда крэшнется - тогда gdb покажет промпт - и тогда смотрите бэктрейс. Либо можно уже пост-фактум смотреть в корке. Либо можно запустить нормальным образом - потом зааттачиться с помощью gdb -p $(pgrep mlnet) - сделать continue и ждать крэша. Нужен бэктрейс именно в момент падения, а не во время нормальной работы. _________________ Download \| Report bugs \| git mirror

Ну что с меня, гуманитария, взять... Smile

Запустил правильным образом. Отпишусь по результатам... Кстати, бывает через час сегфолтится, а бывает через полсуток...

Ок, симптомы понятны, причина - нет :( Ещё вариант посмотреть дамп памяти в месте где крэшится, может будет понятно кто порчу наводит, но не факт. _________________ Download \| Report bugs \| git mirror

Не пинайте сильно, но как посмотреть-то? Гуманитарий я, говорю же... Smile

Там достаточно сложно , мне самому лучше посмотреть. Варианты - выложить корку + бинарник (большой объём) либо дать мне ssh доступ на машину (security) либо можно попробовать в онлайн режиме подебажиться удалённо (долго и неудобно). _________________ Download \| Report bugs \| git mirror

Проблема, похоже, решилась самым неожиданным образом.... Пересобрал MLDonkey с Ocaml 3.10.1 и уже почти двое суток работает бесперебойно! До этого пытался с версиями 3.12.1 , 3.12.0 и 3.11.2 - сегфолты сыпались регулярно... Зарекаться окончательно пока не буду - если что отпишусь... Но раннее осел под нагрузкой у меня более полсуток без сегфолта не работал...
