　　今天在運行java程序的時候報了如上所示的一個錯誤，然后查看日志，通過在百度上查詢，給出了幾種解決方案都不能徹底解決這個錯誤，依然會報錯，再向下看日志時發現jvm堆內存和元空間的使用情況，如下所示：

Heap:
 def new generation   total 44672K, used 13804K [0x05000000, 0x08070000, 0x0a550000)
  eden space 39744K,  30% used [0x05000000, 0x05bab018, 0x076d0000)
  from space 4928K,  37% used [0x07ba0000, 0x07d70208, 0x08070000)
  to   space 4928K,   0% used [0x076d0000, 0x076d0000, 0x07ba0000)
 tenured generation   total 98972K, used 59381K [0x0a550000, 0x105f7000, 0x15000000)
   the space 98972K,  59% used [0x0a550000, 0x0df4d4f0, 0x0df4d600, 0x105f7000)
 Metaspace       used 63522K, capacity 65876K, committed 66048K, reserved 66944K

　　雖然沒有報OOM的錯誤，但是還是存在僥幸心理去改堆內存和元空間的大小，但是還是報錯。

　　在最開始的日志消息中，發現了一個關鍵詞Problematic frame:，下面顯示的是文件名，於是定位到該文件中，發現是用於多個定時任務同時處理該方法造成的，導致報錯，修改程序后，解決問題。
