Module summary

A Memory Supervisor Process

Description

memsup is a process which supervises the memory usage for the system and for individual processes. It is part of the OS_Mon application, see os_mon(6). Available for Unix, Windows and VxWorks.

Periodically performs a memory check:

• If more than a certain amount of available system memory is allocated, as reported by the underlying operating system, the alarm {system_memory_high_watermark, []} is set.

• If any Erlang process Pid in the system has allocated more than a certain amount of total system memory, the alarm {process_memory_high_watermark, Pid} is set.

Alarms are reported to the SASL alarm handler, see alarm_handle
