Ruby Cannot Allocate Memory System


If you do not need the output, you can redirect to null device or use system and let the program write to the terminal. Also, only optimize the "hotspots", which is the code you've measured and determined creates an excessively large number of objects. That would greatly help us prioritize this. Our Rails process takes ~150 MB, so it’s possible that the exact copy won’t fit into the remaining free memory. http://stevemattley.com/cannot-allocate/ruby-cannot-allocate-memory.html

There is some overhead for the ruby process so it's not going to exactly match free. $ ruby -e 'mb = 380; a="z"*mb*2**20; puts "=)"' =) Then make the string slightly This requires over 500mb of memory! RETAINED = [] 100_000.times do RETAINED << "a string" end If we run this and debug with GC.stat(:total_freed_objects) it will return the number of objects that have been released by Ruby. This is already a common pattern when storing external connections, like to Redis, for example: RETAINED_REDIS_CONNECTION = Redis.new Since a constant has a reference to the Redis connection, it will never http://stackoverflow.com/questions/28286002/ruby-cannot-allocate-memory/28290263
