Greetings - I am a 'newbie' to Zimbra. Just tried an installaiton on my RH 5.4 server (32bit). I received this error along with a couple modules not starting. I am not sure if these are 'fatal' or not. When ZMCONTROL STATUS is ran, the following modules do not show as started: Convertd / Spell / Mailbox. Also, 'mysql.server' is not running. I attempted to start the modules using the command as follows: 'ZMcontrol Start convertd' but that did not work. Being a 'newbie' and unfamiliar with Zimbra, thought I'd ask questions before tearing into things. Thanks to all who may offer a suggestion!!
