今天在晚上的時候花了點時間把原本Zimbra 5.0.18 的伺服器升級到最新的Zimbra 6.0.2 版, 升級過程是沒什麼大問題, 不過在啟動的時候老是出現錯誤...

mailbox 一直無法啟動 :(

antispam                Running
antivirus               Running
imapproxy               Running
ldap                    Running
logger                  Running
mailbox                 Stopped
                zmmailboxdctl is not running.
memcached               Running

查看/var/log/message 一直看不出哪裡有問題, 後來找到了 /opt/zimbra/log/zmmailboxd.out , 並看了它的內容發現許多Java不能啟動的錯誤訊息

到網路上找到一篇的解決方法, 在此記錄一下, 只要執行以下命令後 zmmailboxdctl就可以正常啟用了

su - zimbra
zmlocalconfig -e mailboxd_java_heap_memory_percent=30
zmcontrol stop
zmcontrol start
