I've seen in the past INI_Open crashing the server but in the old version (3.1) of it. For a detailed log about the crash, load crashdetect: https://github.com/Zeex/samp-plugin-...etect/releases
Compile with debug info: https://github.com/Zeex/samp-plugin-...ith-debug-info

Next time it will crash, post your server log. On another hand, updating to the latest version of YSI (https://github.com/Misiur/YSI-Includes) is a good idea.
