Linux平台下的core file分析

胡家辉 2010-05-06



第一步：找到core file是由哪个程序产生的

[root@app10 dennis]# file core.11751

core.11751: ELF 64-bit LSB core file AMD x86-64, version 1 (SYSV), SVR4-style, from 'java'

[root@app10 dennis]#

从上面可以看出，该core file是由java产生的。



第二步：用gdb调试器找到问题所在，执行如下命令

[root@app10 dennis]# gdb java core.11751
