If your talking about a memory leak causing server crash? I have the same issue on updates and would be interested in what plugins you have. Im hosted on Host Havoc and this is how i fix the leak. I have a section of nonworkshop mods... in there i uninstall and reinstall RustIO and Rustedit. Then i go to filemanager and delete the steamapps folder. then i go to my tab update server files and hit GO. This reinstalls my steamfolder and updates my umod. This fixes my issue every time. hope this helps. please send me a list of your mods so maybe we can figure out which one may do this.
