可以用这个 gdb 插件定位是哪个 lua 代码触发的。

https://github.com/xjdrew/lua-gdb

看你的堆栈信息，我猜测是那个 loggerx.so 相关的问题

from skynet.

这个能直接调试core文件吗？

打开这个宏 LUA_USE_APICHECK 试试

from skynet.

好的，我试试，这个要服务器下次更新才能试，项目在对外开放测试，一两天宕一次，查来查去最大可能还是申请的内存空间越界或者是否double free 了

from skynet.

看看这个把 LUA_USE_APICHECK MEMORY_CHECK 打开
#1106

from skynet.

这个能直接调试core文件吗？

可以调试 core 文件的，能定位到是哪个 lua 函数的。

从你的堆栈目前只能看出是接收消息 disptch 后挂的。用那个插件应该可以查出是哪行lua代码，调试看看吧。

有点看不懂怎么调试, 如下：
gdb xxx/lua
(gdb) run core文件
(gdb)source lua-gdb.py
这样吗？这样调试不了

from skynet.

不是纯lua编写吗？为什么还需要自己申请内容，管理内容呢？

from skynet.

使用了websocket，外接了一个对消息的处理；现在打算换掉，直接使用skynet自带的websocket

from skynet.

宕机的原因已查明，外部开辟内存不当造成的，使用skynet内置的websocket未出现宕机
