我現在已經有這個問題超過1周了。儘管其他人在這裏使用了類似的問題，但我已經忘掉了。我正在運行Mysql 5.6.10。Mysql提交有時需要幾分鐘才能完成
- "query end" step very long at random times
- UPDATE statements are in "query end state"
- Lots of "Query End" states in MySQL, all connections used in a matter of minutes
它隨機happends。但是，每隔5分鐘左右，提交需要很長時間。插入插入的大小通常在1-2000行左右。
我一直在改變設置這麼多，我的一種失去了它，我決定在這裏創建一個問題。
我的插入/更新是由我的程序生成的sqlfiles。然後我有一個Windows服務每運行1.5分鐘處理文件。我在事務模式下建立了許多sql文件的字符串。它能在5分鐘內完成4次，非常平穩，但5分鐘內1分鐘內就會堵塞。
它通常發生在同一張桌子上，大多數時候它關於插入，但也發生在更新上。所以我懷疑它與我的表結構的事，但你永遠不知道，直到它的解決:)
這是表結構
CREATE TABLE `int_links_root_1` (
`IntLinksRootId` bigint(20) NOT NULL AUTO_INCREMENT,
`UrlId` int(11) NOT NULL,
`Link` varchar(2000) NOT NULL,

`Title` varchar(2000) DEFAULT NULL,
`PageText` varchar(8000) DEFAULT NULL,

我已經嘗試了所有的innodb_flush_log_at_trx_commit不同setti NGS。我確定我的查詢是最佳的，因爲它們偶爾運行得非常快，我幾乎肯定它與我的沖洗有關。我也嘗試禁用autocommit，但它仍然發生。查詢緩存被禁用。但任何想法都是值得歡迎的。也許我的磁盤只是慢點？
該系統沒有在生產，所以我可以重新啓動並測試任何建議。
請讓我知道，如果我可以提供任何更多的細節。
