We use Debian 7 x64 VMs on VMware as Zabbix Proxys. We install the Zabbix components from the official repo, using the following guide:
The packages and the binarys itself work fine. The init scripts also work fine if you use them from the command line.

What can i provide to help you solve that problem?
