一個RUNNABLE狀態的線程hang在了java.io.FileOutputStream.writeBytes方法上
1. 問題背景
web項目要定時拉取其餘系統的數據，用Quartz作了一個定時做業。在聯調時，爲了知道做業的運行狀況，將logback的root logger從warn調到了debug， root logger有兩個appender，一個是ConsoleAppender，一個是RollingFileAppender。css
2. 問題現象
在測試環境windows上，啓動tomcat，觀察tomcat彈出的console，可以打印出日誌信息，沒過多久打出了Quartz相關log，說明定時做業運行了。這時打開瀏覽器，登陸web查看拉取的數據狀況。在打開首頁、登陸等幾個操做後，頁面hang住了，處於假死狀態。觀察tomcat的console，log再也不刷新，沒有新log打出來，包括該打出的定時任務的log。java
同時查看tomcat的8189端口網絡鏈接狀況，netstat -aon | findstr 8189，發現鏈接都是ESTABLISHED狀態，說明瀏覽器的與tomcat一直處於鏈接狀態。mysql
3. 查找緣由
首先想到的就是線程死鎖，經過jstack -l pid > thread_dump.txt導出線程堆棧，發現tomcat的work線程http-bio-8189-exec[8,7,6,5,4]和Quartz的調度線程#0_QuartzSchedulerThread線程都是WAITING狀態，都在等待<0x00000007f5ae3528>鎖，而這個鎖被http-bio-8189-exec-2線程持有，且此線程仍是RUNNABLE狀態。web
一個RUNNABLE的線程會被調度，運行完成後釋放鎖。但過了一會，發現瀏覽器仍是假死狀態，再次jstack查看線程棧信息，這幾個線程棧信息與以前的同樣，狀態沒有改變，說明http-bio-8189-exec-2沒有向下運行。redis
查看線程http-bio-8189-exec-2的堆棧信息，停在了java.io.FileOutputStream.writeBytes方法上，從堆棧上下文ch.qos.logback.core.joran.spi.ConsoleTarget$1.write能夠知道，FileOutputStream寫的目的地是console。從網上查詢，還真在stackoverflow上找到了答案，現象與個人同樣，只不過提問者是log4j。spring
On Windows, if you click in the console window, this will pause the console, e.g. the stdout buffer will fill up, and as the console appender writes serially, your application will hang until you release the console (press enter or so).sql
在Windows上，若是點擊了console窗口會暫停控制檯，若是console appender不停連續的寫，那麼標準輸出緩衝區會被填滿，應用就會hang住直到釋放console(按下回車釋放)。apache
結合個人狀況，在調試的過程當中，不知何時我點擊了console致使它暫停了，而後我去操做web，因爲log級別爲debug，頁面引用的js和css也比較多，這些請求會從filter走到SpringMVC的DispacherServlet，出現了大量spring框架的log寫向console，引發緩衝區滿不能再寫，線程停在了那裏。windows
那麼一個RUNNABLE狀態的線程爲何表現出了‘阻塞’的想象呢？經過查看Thread$State類的java doc，發現RUNNABLE是這樣寫的：瀏覽器
A thread in the runnable state is executing in the Java virtual machine but it may be waiting for other resources from the operating system such as processor.
一個RUNNABLE狀態的線程正在jvm中執行，但它有可能正等待系統資源，好比cpu。
一樣，也能夠是console。
那麼爲何不把這種等待cpu和console的線程再起一個狀態名字呢，我想若是那樣的話，線程模型就過於複雜了，況且要設置一個因程序外狀態變化來設置程序內線程狀態的‘程序’，也不是一件容易的事。
4. 解決方法
在console選中的狀況下，按一下回車。這時馬上就能看到log不停的從console打出來。
