找到原因服務器：採用Linux（1個核CPU，1G內存）

tomcat的server.xml中添加JVM設置： JAVA_OPTS =「 - 服務器-Xms256m -Xmx512m -XX：PermSize = 256M -XX：MaxPermSize參數=512米」
catalina.out的

謝謝。但如何找出哪些系統日誌文件？使用'ls -l/var/log /'，不喜歡最新的更新日誌文件 –
不應該有很多日誌需要排序，因爲很多系統文件都是滾動的，所以在這個例子中我不認爲搜索是必要的。尋找一個特定的日期/時間。例如，在一個centos系統上，你可能有一個消息，yum.log和安全文件。 –
