感謝在粉絲群里分享的這篇崩潰日志和服務(wù)器日志w，我就拿來用啦。別問我為什么突然復(fù)活，只是在放寒假(

這個崩潰應(yīng)該是在1.14加入一個Server?Watchdog（服務(wù)器看門狗）引起的，這是一個線程，當(dāng)有滯后（Lag）過久時它就會自動結(jié)束服務(wù)器進程。

由于這個崩潰是因為服務(wù)器滯后/卡頓造成的，因此具有一定的隨機性，這取決于你的服務(wù)器在什么時候出現(xiàn)了滯后以及滯后的程度。

以上兩篇日志均做了部分刪減和修改，以節(jié)省篇幅和保護隱私

解決方案：

1. 將Watchdog滯后自動關(guān)閉設(shè)置到更久一點或關(guān)閉它。

在服務(wù)器文件目錄下，你應(yīng)該能找到server.properties文件，用文本編輯器之類的軟件打開它，將里面的max-tick-time后面的數(shù)值修改成比60000還大的數(shù)字（滯后更久再關(guān)閉服務(wù)器，該數(shù)字以毫秒為單位，默認(rèn)滯后60秒自動關(guān)閉服務(wù)器）或者是-1（不檢測滯后，該選項在14w32a中添加）。

2. 自行提防服務(wù)器會引起卡頓的內(nèi)容并做好相關(guān)處理措施。

3. 提升你服務(wù)器的運行內(nèi)存。

雖然在之前的文章里面沒有有目的地請你們幫忙點個贊（雖然我也不怎么在乎贊嘎嘎嘎，能幫到就好），但是我發(fā)現(xiàn)如果贊少的話會影響文章的推廣，不怎么利于及時幫助其他有相似問題的玩家，所以還是希望如果這篇或其它文章對你有用的話，麻煩請你點個贊喵，謝謝辣w
