   I´ve installed a Maia server for a high volume of emails site, about 400 thousand messages a day. The server is a Dual Xeon 3.0 GHz with 2 Gbytes of memory. I´ve installed CentOS 4.4 a perl with modules installed by CPAN.
   Initially the machine started freezing with a kernel panic message. I´ve rebooted with a not SMP kernel and everything seems fine.
   Is this machine enough? Any ideas about the kernel panic? Whish is the preferred distribution to be used with Maia, is ther´s one?
 
   I have lots of doubts but I´ll start with this?
 
   Best regards,

Centos should work well, My next choice would be Ubuntu or a
fedora base, or
maybe Suse if the recent PR mishap doesn't turn you off.

A kernel panic in SMP seems like some sort of problem with
Linux and your
hardware, which seems weird.  See if there's a kernel update
that you need to
grab; or try to compile your own.  In any case, don't
overwrite existing kernels
or files!  Add them to the boot menu, but keep the originals
around so you can
boot if the compile fails.

You might ask in the Centos support channels about the
panic; They would be able
to help you more.  I don't see Maia being directly
responsible.

As far as enough power, it varies from site to site; you may
want to have a
dedicated mysql server, and max out the RAM... the more RAM
the db has, the
better (assuming you also tune mysql to use the RAM)

   Hi,
 
   I´ve installed a Maia server for a high volume of emails site, about 400 thousand messages a day. The server is a Dual Xeon 3.0 GHz with 2 Gbytes of memory. I´ve installed CentOS 4.4 a perl with modules installed by CPAN.
   Initially the machine started freezing with a kernel panic message. I´ve rebooted with a not SMP kernel and everything seems fine.
   Is this machine enough? Any ideas about the kernel panic? Whish is the preferred distribution to be used with Maia, is ther´s one? 
 
 
I doubt it's anything related to Maia OR centOS specificially (since it's source based upon RH EL 4) and more than likely it's a hardware issue.  We have 10 CentOS 4.4 and 30+ Centos 3.8 without any issues and are running CentOS 4.4 on our 2 anti-spam servers (many different hardware configs)  
  • check your log files to see what the error is
  • make sure you have the latest kernel via yum updates
My guess, without seeing the log files, is it's memory or CPU related
