I'm using FileZilla client to upload plugin files to my server hosted by gameservers.

Each time I upload, my server restarts. I'm unsure if this is a result of a crash or if this is a new, as in the past I was able to upload multiple .cs files at a time with no performance hit at all from the server. If it's related, this occasionally occurs when I update a config file and "refresh" them via console with oxide.reload [plugin], while adding new plugins altogether restarts the server each time.

That said, after the restart, the plugin is sucesfully loaded so that isn't an issue fortunately.

Any help would be much appreciated, thank you.

Hey!
Try to contact with your hosting support. And don't forget to check your logs.

It's a problem of Ram Limit, they have very limited resources.
