assert(top == 2) core dump at lua-skynet.c:42

[bhhbazinga]

每次开服在1~3个小时内总会跑到 lua-skynet.c :42行的assert(top == 2)。
请问云风这有可能是什么原因造成的呢，我该怎么查能给点建议吗？谢谢。
bt如下:

定义 MEMORY_CHECK https://github.com/cloudwu/skynet/blob/master/skynet-src/malloc_hook.c#L13

以及定义 LUA_USE_APICHECK https://github.com/cloudwu/skynet/blob/master/3rd/lua/luaconf.h#L696-L702

然后再查。
