Hi,

Today I found that the mail server is hanged suddenly. All system resources were hanged. I could only restart the machine to get it work. After that, I traced out the messages log and there were Zimbra error (Only Zimbra is run on the server). Is there any idea for the problem?

OS & Version: zcs-3.0.0_M3_436a.FC3
