From: nobu@... Date: 2015-04-17T02:52:50+00:00 Subject: [ruby-core:68914] [Ruby trunk - Bug #10942] Suspected memory leak Issue #10942 has been updated by Nobuyoshi Nakada. Backport changed from 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN to 2.0.0: DONTNEED, 2.1: DONTNEED, 2.2: REQUIRED Thank you, it's very helpful. ---------------------------------------- Bug #10942: Suspected memory leak https://bugs.ruby-lang.org/issues/10942#change-52179 * Author: Johan Lundahl * Status: Open * Priority: Normal * Assignee: * ruby -v: ruby 2.2.1p85 (2015-02-26 revision 49769) [x86_64-linux] * Backport: 2.0.0: DONTNEED, 2.1: DONTNEED, 2.2: REQUIRED ---------------------------------------- There seems to be memory leaking when calling Aws::SQS::Client#receive_message in Ruby 2.2.0 and 2.2.1. I am not very good at memory/object allocation profiling in Ruby, but I know for sure that there must be some issue, because my SQS workers run out of memory every day. See gist https://gist.github.com/quezacoatl/7657854f371edcb5d8e6 to reproduce. I've added output.txt for my output for different Ruby versions. Ruby 2.1.2 works fine. I'm sorry that I cannot pinpoint the exact issue. Perhaps somebody with better profiling skills can do this? ---Files-------------------------------- 0001-stringio-avoid-STR_NOFREE-due-to-constant-string.patch (1.49 KB) -- https://bugs.ruby-lang.org/
