I just did a fresh install with the latest download. I installed to a VirtualBox VM, 8GB disk and 1GB RAM allocated. I gave it 2 NICs, one set to NAT and the other as the internal VBox network.
Another Win XP VM with one NIC set to the internal VBox network. Fairly minimal XP machine, MS Security Essentials, Firefox and all latest updates.
Zentyal boots up ok and everything works fine. It's routing traffic to the XP VM. If Zentyal isn't running, XP VM cannot access anything. While sitting at the Zentyal desktop, I opened User Console and ran top.
Right now the XP VM is not running and Zentyal has uptime of over 1 day. While watching top, perl seems to hold steady at 25% CPU time. I have no idea what it's doing but it's constantly using CPU time.
Setting up in a VM was the first step in testing Zentyal to see if I want to try it in production. It's passed pretty much everything I've tried/want to do with it... but using a constant 25% CPU time is a deal breaker. Maybe I turned something on in the web config that is causing it. I don't recall setting up anything other than the 2 NICs, DHCP and DNS. I really wanted to keep it simple before trying more.
Any ideas why perl is constantly running and using so much CPU?
