There may be situations when you do not want a host to be scavenged if a specific process is running on that host. For example, there may be high-priority non-Symphony application processes that require the host. Symphony allows you to specify these processes in a list will cause the host to be closed if the process is running on that host. When Symphony detects one of these processes are running, it automatically closes the open host or prevents the host from opening for future scavenging. These processes are specified in a list known as the close process list. You can populate this list when you configure host scavenging.
