Downloading latest version of metamod resolved for me.
http://www.metamodsource.net/snapshots
I had used the latest snapshop on the stable branch.
Downloaded metamod/Installed metamod
Started server
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
