>Description:
The default values for kern.ipc.shmmax and kern.ipc.shmall are too low for several applications (such as zabbix_server).  As a result they cannot be started without first running sysctl from the command line or updating /etc/sysctl.conf with something like:

  kern.ipc.shmmax=134217728
  kern.ipc.shmall=16384
>How-To-Repeat:
Update system, install and configure anything that requires a karge amount of RAM, then attempt to start.
>Fix:
Define larger and more reasonable default values for kern.ipc.shmmax and kern.ipc.shmall.
