The answer is in your heap: debugging a big memory increase in Ruby on Rails
I recently participated in an interesting series of debugging sessions tracking down the source of a large increase in memory when upgrading a Rails application. We ultimately tracked down the cause using John Hawthorn’s Sheap heap analyzer and successfully submitted a patch to Rails. I thought it was interesting enough to write up because maybe the general approach to debugging memory issues woul

HEAP テーブルは、ハッシュインデックスを使用し、メモリに格納されます。これによって処理は速くなりますが、MySQL がクラッシュすると、このテーブルに格納されたすべてのデータが失われます。HEAP は、テンポラリテーブルとして非常に便利です。 MySQL の内部 HEAP テーブルは、オーバフローエリアなしの 100% 動的ハッシュを使用します。フリーリスト用の余分な領域は必要ありません。また、HEAP テーブルでは、ハッシュテーブルで一般に見られる削除 + 挿入に伴う問題も起こりません。 mysql> CREATE TABLE test TYPE=HEAP SELECT ip,SUM(downloads) AS down -> FROM log_table GROUP BY ip; mysql> SELECT COUNT(ip),AVG(down) FROM test; mysql>

StrongLoop - How-to: Heap Snapshots and Handling Node.js Memory Leaks
How-to: Heap Snapshots and Handling Node.js Memory Leaks by Marc Harter Oct 2, 2013 / How-To _In the beginning, there were memory leaks in JavaScript … and we could not have cared less._ _Then there was Ajax … and we started to care._ _Then there were these long-running Node processes on our production servers … and we really cared a lot!_ Node memory leaks happen. Usually they occur in production
The Java Virtual Machine (JVM) running IntelliJ IDEA allocates some predefined amount of memory. The default value depends on the platform. If you are experiencing slowdowns, you may want to increase the memory heap. In the main menu, go to Help | Change Memory Settings. Set the necessary amount of memory that you want to allocate and click Save and Restart. This action changes the value of the -X

This facility can be useful for Figuring out what is in the program heap at any given time Locating memory leaks Finding places that do a lot of allocation The profiling system instruments all allocations and frees. It keeps track of various pieces of information per allocation site. An allocation

heap2exec is a simple utility for building stand-alone executables from SML/NJ heap images. heap2exec wraps the binary smlnj runtime image and an smlnj heap image into one executable image. heap2exec is a shell script that makes use of the heap2asm tool. The heap2asm tool is installed in the smlnj bin directory when running config/install.sh if heap2asm is specified in config/targets. heap2asm is
I have a Scala data processing tool which is failing with a java.lang.OutOfMemoryError exception. The tool needs to make a couple passes over a large data file (the one I'm working on is over 700MB), so it would be convenient if the entire thing could be stored in memory. I run the tool from the command line or from a Bash script using the "scala" runner. How do I increase the JVM heap size for th

Benchmarking Ruby's Heap: malloc, tcmalloc, jemalloc — Engineering Blog
Last week's post talked about different kinds of Ruby objects: some are contained in the 64-bit reference directly, some use up a 40-byte "Slot", and some use a Slot and a chunk of heap. Let's talk about that last set of objects. "The Heap" isn't specifically a Ruby concept. It's a standard part of Unix processes. Other than garbage collection, Ruby doesn't do much that's special or unusual with t

You'd have thought that memory leaks were a thing of the past now that we use .NET. True, but we can still hit problems. We can, for example, prevent memory from being recycled if we inadvertently hold references to objects that we are no longer using. However, there is another serious memory problem in .NET that can happen out of the blue, especially if you are using large object arrays. Andrew H

Docker memory resource limits and a heap of Java - #NoDrama DevOps
Docker memory resource limits and a heap of Java by Stephen Kuenzli | Oct 3, 2019 | DevOps, Docker | 0 comments Ok, so maybe you’re convinced why you need to set limits for container resource usage, especially when running on shared container application platforms like ECS, Kubernetes, and Swarm. In this post, I’ll show you how to set memory limits for a basic Java web app built with Spring Boot.
This is not a problem that is necessarily solvable by changing configuration options. Changing configuration options will sometimes have a positive impact, but it can just as easily make things worse, or do nothing at all. The nature of the error is this: #include <stdio.h> #include <string.h> #include <stdlib.h> int main(void) { void **mem = malloc(sizeof(char)*3); void *ptr; /* read past end */
How the Ruby heap is implemented October 12, 2007 at 2:44 pm · Filed under Ruby It’s been a while since I’ve worked on Ruby’s garbage collector, and my memory about it is getting dusty. At the time, I noticed that there’s very little documentation about the Ruby interpreter implementation. There are little pieces of comments here and there, and a few slides and emails all over the Internet, but
【MySQL】tmp_table_sizeを増やすときはmax_heap_table_sizeもセットで増やすこと at softelメモ
問題 これどうするといいですか。 Created_tmp_disk_tables → 赤文字で警告（phpMyAdminの状態表示では） → ステートメント実行中にサーバがディスク上に自動生成した一時テーブル数。Created_tmp_disk_tables の値が大きい場合は tmp_table_size の値を増やしてディスク上ではなくメモリ上に一時テーブルを構築した方がよいかもしれません。 答え tmp_table_size を増やす。 一緒に max_heap_table_size も増やす。 MySQLの一時テーブルは最初メモリ内のheap テーブルで作成されるが、テーブルのサイズがmax_heap_table_sizeまたはtmp_table_sizeを超えてしまうとディスクを使うMyISAMに変換される。 なるべくメモリ内で完結できるように、対策する。 SET tmp_tab

Abstract¶ We propose to introduce "2nd" GC managed heap named "Transient heap" into MRI, instead of malloc management heap. Employied GC algorithm is similar to "generational" "copying" GC algorithm. This technique can reduce problems of malloc'ed heap. Background¶ MRI and malloc¶ MRI manages memory by GC managed heap and malloc'ed heap. Objects are allocated from GC managed heap. However, each ob

Heap sizes Initial heap size of 1/64 of physical memory up to 1Gbyte Maximum heap size of 1/4 of physical memory up to 1Gbyte However, above algorithms are just for reference, it may vary in different

Chrome DevtoolsにはHeap Snapshopという機能があり、この機能を使うと任意のタイミングでJavaScriptのメモリの詳細を見ることができます。インスタンスがどれだけ存在するかやどの変数から参照されているかなどがかなり細かくわかります。 このHeap Snapshotはメモリリークを見つけるのに役立ちます。そこで、setIntervalを使ったコードでわざとメモリリークさせてみたところ、Heap Snapshot上でそのメモリリークを確認することができませんでした（あたかもリークしてないように見えた)。 <div id="count">show count</div> <div id="end">end</div> <script> function Sample() { this.count = 0; var self = this; this.id = setI
Fibonacci heap - Wikipedia
In computer science, a Fibonacci heap is a data structure for priority queue operations, consisting of a collection of heap-ordered trees. It has a better amortized running time than many other priority queue data structures including the binary heap and binomial heap. Michael L. Fredman and Robert E. Tarjan developed Fibonacci heaps in 1984 and published them in a scientific journal in 1987. Fibo

Plugging Ruby Memory Leaks: heap/stack dump patches to help take out the trash. - kなんとかの日記
