limit node memory usage node needs to be told how much space it can usage, otherwise it keeps allocating and we cannot keep it under 50M. keeping old space to 30M, lets the memory hover around 40M there are many options to v8 but I haven't explored them all: --expose_gc - allows scripts to call gc() --max_old_space_size=30 --max_semi_space_size=2048 (old/new space) node first allocates new objects in new space. if these objects are in use around for some time, it moves them to old space. the idea here is that it runs gc aggressively on new space since new objects die more than old ones. the new space is split into two halves of equal size called semi spaces. --gc_interval=100 --optimize_for_size --max_executable_size=5 --gc_global --stack_size=1024 http://erikcorry.blogspot.com/2012/11/memory-management-flags-in-v8.html http://jayconrod.com/posts/55/a-tour-of-v8-garbage-collection https://code.google.com/p/chromium/issues/detail?id=280984 http://stackoverflow.com/questions/30252905/nodejs-decrease-v8-garbage-collector-memory-usage http://www.appfruits.com/2014/08/running-node-js-on-arduino-yun/ note: this is not part of shebang because linux shebang does not support args! so we cannot pass node args as part of shebang. 2015-09-10 19:18:02 -07:00			`ExecStart=/usr/bin/node --optimize_for_size --max_semi_space_size=5 --max_old_space_size=30 /home/yellowtent/box/oauthproxy.js`
