After upgrading from 6.010 to 7, everything seems to be working fine. However when I reboot or shutdown the server, at the very end I get this message for all Zimbra services:

Stopping cannot create /opt/zimbra/data/tmp/zmcontrol.out.kxeAA: Read-only file system
cat: /opt/zimbra/data/tmp/zmcontrol.out.kxeAA: No such file or directory Failed.

I get this for all services: logger, zmconfigd, ect....

Is this normal??
