Can reloading(unloading) heavy plugin cause server crash?
 

I have built a plugin that has lots of arrays containing player info(previous class, team, etc to be used in match servers)

Sometimes when i reload or unload this plugin the server crashes(especially when the server has many players)

is there any way to fix it?

If the plugin weights more than 100 kilograms, this can happen yes :)

I don't think the amount of data / array has anything to do with it, this would be weird. It's more likely that some extension is causing the crash. For example when you register a callback function in your plugin with some extension and the extension doesn't correctly unregister the callback function on unload, it will probably crash. Make sure to unregister any hooks / callbacks, if the extension provides a way.

A stacktrace from the linux GDB debugger would be helpful in order to exactly determine where is crashes.
