SYSAGT–338 Agent Process Consumes Excess Memory
The System Agent would consume an excess amount of memory after having been receiving scans from unexpected sources such as a vulnerability scanning tool.

Optional workaround for lesser versions
set the following in the agents agentparm.txt file and restart to limit the agents memory usage to 1gb.
oscomponent.jvm.x.options=-Xmx1g

NOTE - the memory issues typically happen as a result of port scanner from accessing the agent's port.
