The 'security memtarget' command sets a soft limit on how much memory ConferenceRoom will use. It can be set either in kilboytes or as a percentage of physical memory (on platforms where ConferenceRoom can determine how much physical memory is present). As memory gets close to the target, ConferenceRoom will beging refusing to perform expensive commands. If memory usage exceeds the target, new connections will not be allowed.
/as security memtarget 40%%
/as security memtarget 500KB
This will protect systems with limited memory resources. This setting is normally not needed as only very large event/client servers will ever use enough memory on a system to impact it.
