Resolution

Confirm that all permissions are correct on the new server: 1. As root, run the zmfixperms command to repair any potential permissions problems with files under /opt/zimbra:

 /opt/zimbra/libexec/zmfixperms

2. If you need to check /opt/zimbra/store and /opt/zimbra/index as well, you will need to use the -extended option. This will take much longer to run – potentially several hours in large environments – so run it only if necessary. Run this command as root:

 /opt/zimbra/libexec/zmfixperms -extended 

zmlocalconfig -e zmdisklog_warn_threshold=90
zmlocalconfig -e zmdisklog_critical_threshold=98

sudo kextunload -b com.apple.iokit.BroadcomBluetoothHostControllerUSBTransport
sudo kextload -b com.apple.iokit.BroadcomBluetoothHostControllerUSBTransport

Cpanel'de yer açmak gerekirse önce error_log ları silmenizde fayda var.
Aşağıdaki komut home ile klasörü içindeki  tüm logları silebilirsiniz. 

find /home -name 'error_log'  -exec rm {} \;
