Memory Overload Protection

Communications Server enables you to regulate incoming HTTP and SIP requests based on the memory usage. Memory overload protection can be activated or de-activated both during installation and in runtime.

To enable memory overload protection, set the MemOverLoadRegulation property to true. By default, this value this set to false. Use the following command to set this property:

asadmin set config.sip-container.property.MemOverLoadRegulation=true

You can configure the following threshold levels:

• MemHttpThreshold - All incoming HTTP requests are rejected and 503 responses are sent out, when this threshold is exceeded.

• MemIrThreshold - Initial incoming requests are rejected and 503 responses are sent out when this threshold is exceeded.

• MemMmThreshold - All incoming HTTP and SIP requests are rejected when this threshold is exceeded.
