I'm at the point where I'm fine tuning Zimbra after our recent migration. I'm trying to increase the zimbraMessageCacheSize, issuing the command as the zimbra user.
zmprov ms zimbraMessageCacheSize 104857600
It fails each time. Not sure where I'm going wrong with the syntax, any thoughts would be appreciated. I also added it to zmlocalconfig and it shows up, but after a zmcontrol stop/start, zmprov gacf | grep zimbraMessageCacheSize still shows the default value.
