similar to: mongrel garbage collection

Hello, I''m running a Rails application which must sort and manipulate a lot of data which are loaded in memory. The Rails app runs on 2 mongrel processes. When I first load the app, both are 32Mb in memory. After some days, both are between 200Mb and 300Mb. My question is : is there some kind of garbage collector in Mongrel? I never see the two Mongrel processes memory footprint

Hi One of the two mongrel processes has died in the middle of the night four times in the past 9 days, and I need help debugging this. Each time the symptoms are the same: * Each time I can restart the process via cap -a restart_app. * Before the restart, there is nothing unusual in production.log or mongrel.log. * During the restart, about 100 repetitions of an error message are generated in

Morning Folks, As most of you know there were a few people who had the following three bugs: * CLOSE_WAIT: Lots of sockets in CLOSE_WAIT state. * 99% CPU: Mongrel''s getting "stuck" pegged at 99% CPU. * LEAK: Memory leak. I''ve successfully fixed these bugs or attributed them to one main cause: pstore. First, the memory leak was because of a bug in how the GC in Ruby

I''ve been trying to track down the culprit of erratic behaviour and crashes on my production server (which is split into a number of Xen instances), so set up a staging server so that I could really try to get to the bottom of it. The staging server (also split with Xen) is set up pretty much identically as far as the mongrel_cluster server is concerned (the production box has two

As I''ve mentioned before, Sync and Mutex are very similar, and Mutex is very simple. Their locking algorithm (for exclusive locking) is essentially identical. And in some detailed examinations of Mutex''s behavior, there''s nothing superficially wrong with it. It''s pure ruby, so there are no funny memory allocations at the C level, and it essentially operates

Hi, my mongrel has crashed with following errors in the logfile: ** Starting Rails with development environment... ** Rails loaded. ** Loading any Rails specific GemPlugins ** Signals ready. TERM => stop. USR2 => restart. INT => stop (no restart). ** Rails signals registered. HUP => reload (without restart). It might not work well. ** Mongrel 1.1.3 available at 0.0.0.0:3000 **

Hi all, My environment is ruby-1.8.4, rails 1.2.2, mongrel 1.0.1, linux 2.6. Now, i have a problem on memory leaks with mongrel. My site is running 5 mongrel processes on a 2G RAM machine, the memory of each process grows from about 20M to about 250M, but it never recover to the initial 20M, so i had to restart the mongrel processes once per day. The load is about 1M hits per day. Waiting for

Hi, It would be nice if Mongrel would do multiapps in one Mongrel instance. For the moment, I have one Mongrel for each app of my server, each on a different port. For example: http://server:8080/app1 http://server:8080/app2 instead of: http://server:8080/ http://server:8081/ Is that planned?

Guys, Just for fun, I tried to see (I know, a silly way to test it) how much overhead we have calling the C functions of the extensions. the benchmark script and the results: http://pastie.caboo.se/128646 The naive C extension: http://pastie.caboo.se/128647 I compared 1.8.6 (VC6 and mingw builds) against a fresh checkout of ruby trunk. What I understand from that is 1.9 is slower than 1.8

My production server is using mongrel_rails on Ubuntu linux. With Firefox I can reach my production server with the URL: www.mydomain.com:3000/ but I can''t reach my production server with the URL www.mydomain.com/ Is there a way to configure mongrel so that I can reach my production server with the URL www.mydomain.com? -- Posted via http://www.ruby-forum.com/.

I heard about a new mongrel plugin or version that''s single threaded and uses non-blocking IO with events. It''s called something like "swifty fly". Anyone have a link for it? Thanks.

I have a periodically_call_remote call in a partial running at 0.20 times a second. <%= periodically_call_remote(:update => ''ack_distance_output'', :frequency => 0.2, :url=>{:action => :ackAdjustDistance}) %> the action looks like this def ackAdjustDistance @calMessage = Calibration.getMessage

Hi. I''m a fairly new mongrel user and have a scenario that I wanted to run by you all, see if anyone''s synapses connect -- mine def. aren''t! I''m running a fairly simple rails app through a mongrel cluster (2 mongrels). This site is consistently sloooow -- memory on the server is regularly paging (and shouldn''t be). ssh-ing in and running top shows

I am using BackgrounDRb to resize images after they are accepted into our system. However, it has become clear that this creates a memory leak. I''m not sure exactly where the leak exists, but I don''t think it''s in my own code as it is presently being used in production and has resized thousands of images without a leak occurring, thanks to calling GC.start

Okay, I got off my duff this week and have been finishing Mongrel support for IOWA. I now have two handlers that I need to test. One is similar to the Rails handler, passing request handling to IOWA threads in the same process, and the other allows one or more Mongrel processes to pass requests to one or more separate IOWA processes, with session affinity. Is there any set of standard sorts of

A couple of questions please: What is the benefit of having more than one Mongrel/Rails instance on the same machine, could one instance not serve as many requests as say three instances? Is Mongrel Cluster a Apache add-in (like mod_*) or a separately running load balancer which runs on a separate port, I could not work it out from the sample Apache config... |# Redirect all non-static

Hello Mongrels, Mongrel 1.1 is out with fullblown JRuby support, some reorganization, and some bugfixes. Also, Mongrel_cluster has been updated to 1.0.4.

Hey all Im working on improving the speed of my application. Ive taken on board everything that has been said on this forum so far, im using httperf to benchmark and try to improve performance. However, I have some question marks over how best to go about improving performance in certain areas.... With no caching or such like deployed the application runs at an rather slow 35 - 38 req/s. A

I have a rails application that runs on multiple mongrels and I would like to make the log files non-interlacing. Are there any logging modifications/other loggers out there that I could use to create process safe logging? Thank you, Matt Margolis
