Недостаточно системной памяти в пуле ресурсов «внутренний»

Question

Связанный сервер SQL Server 2008 и специальные вставки вызывают быструю утечку памяти, которая в конечном итоге приводит к тому, что сервер перестает отвечать на запросы, и заканчивается следующей ошибкой:

Msg 701, Level 17, State 123, Server BRECK-PC\SQLEXPRESS, Line 2
There is insufficient system memory in resource pool 'internal' to run this 
query.

Location:        qxcntxt.cpp:1052
Expression:      cref == 0
SPID:            51
Process ID:      1880

Сервер не отвечает на запросы до перезапуска SQL Server.

Используемое программное обеспечение:

• 64-разрядная версия Windows Vista Ultimate 6001 с пакетом обновления 1

• Microsoft SQL Server 2008 (SP1) - 10.0.2734.0 (X64) 11 сентября 2009 г. 14:30:58 Copyright (c) 1988-2008 Microsoft Corporation Express Edition с расширенными службами (64-разрядная версия) в Windows NT 6.0 (сборка 6001: пакет обновления 1)

• Драйвер SAOLEDB.11 из SQL Anywhere 11.0.1.2276

Установка максимального объема памяти сервера (МБ) на 2048 не помогла.

Добавление различных значений -g (например, -g256;) к параметрам запуска сервера не помогло.

Использование DBCC FREESYSTEMCACHE ('ALL'), DBCC FREESESSIONCACHE и DBCC FREEPROCCACHE не помогло.

Установка пакета накопительных обновлений 4 до SQL Server 2008 с пакетом обновления 1 (SP1) не помогла, даже несмотря на то, что в ней исправлено симптом утечки памяти, связанный с использованием связанного сервера.

Отделение запроса SELECT ... ROW_NUMBER () OVER ... от INSERT не помогло. Эксперимент показал, что комплекс SELECT не вызывал утечку памяти, а INSERT -

.

Изменение кода для использования специального синтаксиса «INSERT INTO OPENROWSET» вместо связанного сервера не помогло; код ниже показывает использование связанного сервера.

Утилита sysinternals.com Process Explore показывает, что использование памяти было связано с sqlserver.exe, а не с библиотеками DLL, используемыми драйвером OLEDB SQL Anywhere SAOLEDB.11.

Обратите внимание, что версия связанного сервера (прокси-таблицы) SQL Anywhere работает нормально, «перетаскивая» 1,9 миллиона строк из таблицы SQL Server 2008 в базу данных SQL Anywhere 11 за одну транзакцию. Логика, показанная здесь, является попыткой использовать функцию связанного сервера для «выталкивания» строк; в том же направлении, другой синтаксис.

Код следует; 4 ГБ ОЗУ исчерпано после трех или четырех выполнений EXECUTE copy_mss_t2:

Answer 1

Вам не нужно очищать временную таблицу #t после каждой итерации? то есть добавить TRUNCATE TABLE #t в конце вашей процедуры? Я думаю, что временная таблица #t существует до тех пор, пока не закончится ваша сессия, а не до окончания хранимой процедуры. SELECT INTO просто добавляет к существующему #t, но не заменяет его.

Другое дело - использовать постоянную таблицу, а не что-то, хранящееся в базе данных tempdb #tables.

Answer 2

Проблема заключается в использовании связанного сервера через поставщика SQL Anywhere 11.0.1 SAOLEDB.11 для вставки данных в целевой столбец, объявленный как размер, превышающий VARCHAR (8000). Вот упрощенное воспроизведение:

-- Overview: SQL Server 2008 suffers from a fatal memory leak
--    if an attempt is made to use a linked server and the 
--    SAOLEDB.11 provicer to copy data from SQL Server

--    column is OK but VARCHAR ( 8001 ) is not. The actual string 
--    length is not an issue, nor is the fact that the SQL Server
--    column is declared as TEXT. The memory leak is faster if

Answer 3

У меня была похожая проблема, мой код содержит использование простой таблицы #temp в цикле, что вызвало это, и я заменил ее постоянной таблицей.

Кажется, работает.

Спасибо Нэвин

Answer 4

Вместо использования временных таблиц, можете ли вы попробовать использовать таблицы переменных?

например.

DECLARE @ResultTable TABLE (TableId INT PRIMARY KEY, ... etc)

INSERT INTO @ResultTable
SELECT TableId, ....
FROM mss_t2 

... etc. ...

Answer 5

Вы можете попробовать запустить вставку партиями вместо всего набора данных сразу.
