I have Zimbra running fine, with no quirks, on a RHEL 4 ES u3 (32 bit OS)* server that I set up about 2 weeks ago.

On a 2nd server, instead of Red Hat, I used CentOS 4.3 (64 bit), which is supposed to be binary compatible w/RHEL 4 u3 (64 bit), same source code, etc.

But i'm getting the same symptoms as Luca, although I don't get any warnings about missing modules. As zimbra user (su - zimbra), the command "zmcontrol start" shows all services as starting successfully (usually, a few times the MTA has failed).

However, a check with zmcontrol status then shows that anti-spam, anti-virus, logger and snmp are stopped.

I can log into the admin account's email (but not the admin panel, for some reason, despite firewall ports being set the same on both machines) on the CentOS box, and create an email, etc.

This is totally not your guys job, to test out a product that is advertised for Red Hat on CentOS, but have you done any testing internally that has shown differences in Zimbra running on one vs. the other?

Or should I cave in and buy another Red Hat subscription?

[ Note that I edited this post: The 1st server is at a dedicated hosting facility, and although the CPU is EMT64, the guys who installed RHEL used the 32 bit version, not the 64 bit].

***UPDATE:

So I'm going to do my Linux-newbie best to try to figure out how to set the env vars so that PERLLIB and PERL5LIB are pointing to the right 64-bit libraries for zimbra user context (did that make sense?). From the posts above, and RobRankin (thanks for the help!) it seems like just editing the .bashrc file (?).

If I get it working, I'll post newbie-friendly tips (it's been a looonggg time since I was working on a *nix system, and that was Solaris...
