1.检查所有加锁的地方，是否加锁和解锁一一匹配，错误返回是否忘记解锁。。。。 2.所有函数的地方进出打日志，定位到哪个函数，然后再进一步分析。。。

我是PRO*C遇到 今天刚遇到 skgesigOScrash这种 然后局部变量的地址被改了 你最终有没有找出什么问题 ORACLE 2014年别人提问的支持回答给的是程序泄露 或者可能ORALCE新问题 。BIM的某个一大堆英语 然后说是ORACLE的BUG 。也有人分析他的插入的东西 什么么reject 然后core 。个程序有的运行半年也没有这个错误 。这个4台在运行 有一台出现这个错误。我那个PRO*C使用的是单线程的 。但是core 0是在 libpthread 然后后面类似一样 再出现信号句柄调用 ，接着才是我那个堆栈的局部变量穿到函数里 地址变了 在取指加锁

[Datrilla]

我还看到一个Oracle OCI关闭core 的东西的 这种我也没懂
