Its a bit complex to track the exact amount of memory inside the
Erlang VM in Erlang source code to do<br>
something useful with the information due to the various memory
pools and the garbage collection.<br>
However, there is some code at
<a class="moz-txt-link-freetext" href="https://github.com/okeuday/erlang_term/">https://github.com/okeuday/erlang_term/</a> which returns the upper
limit<br>
for some Erlang term's memory consumption. The result can then be
used in Erlang source code for<br>
determining how to avoid excessive memory consumption, to avoid a
crash. CloudI uses this to limit the<br>
incoming queue of a CloudI service with the queue_size service
configuration option<br>
(<a class="moz-txt-link-freetext" href="http://cloudi.org/api.html#2_services_add_config_opts">http://cloudi.org/api.html#2_services_add_config_opts</a>).<br>
