I’m not sure exactly what type of “crash” they are seeing. We have regularly had a damaged temp file, and then our data file closes. On one server, it closes gracefully. Reopens with no problem. On the other server, yesterday it killed the data file. I had to revert to a backup.
On those two servers, StartupRestoration is now off. It if happens again on our third server, we will also turn it off there.
fmsadmin set serverprefs StartupRestorationEnabled=false
