I am using ZCS 5.0.5 on Fedora Core7 , x86 OS. But,my server hardware is based on x86_64 bit architecture. So, Will it create any problems fom ZIMBRA? i.e. Zimbra Mail server slow response,Mail server crashed.............etc etc etc.........

I am using a common password for ZIMBRA as well as for my linux root account. By changing root password & Zimbra Admin password,will it create problems?

I am afraid to change the password bcoz I installed ZCS by putting my 7 days efforts.If someone goes wrong,then I will be in trouble.

Please respond.
