If a command dosent work, take it off. Its normally not commands that crash the server. Only rcon does. I know there glitches in mani, but its not commands. Its conflicts in the mod. Plus the server needs to be rebooted once a day. It helps keep out lag, choke, and server crashes.
Sorry if im intruding on buisness thats not of my own, just 8 years of hosting servers helps with knowing these things.
