Downloading latest version of metamod resolved for me.
I had used the latest snapshop on the stable branch.
Downloaded metamod/Installed metamod
Server downloaded new gamedata files and crashed
When it came back up it works fine.
Tested loading server from start script and no crash.
One of my servers I had to go into steamcmd and do an app_udpate 232330 -validate because it kept crashing with only one plugin loaded even after re-installing all sm files
