According to the mongrel_cluster.yml file you provided, you''re starting only 14 mongrels, but in your proxy balancer config you have 30 mongrels listed on ports 21000 - 21029. In this scenario, if apache tries to proxy to any ports higher than 21014 then you''ll get a proxy error as a mongrel doesn''t exist on that port. Or am I missing something? -----Original

Afternoon I upgraded our oss''s from 1.8.3 to 1.8.4 on Saturday (due to https://bugzilla.lustre.org/show_bug.cgi?id=22755) and suffered a great deal of pain. We have 30 oss''s of multiple vintages. The basic difference between them is * md on first 20 nodes * 3ware 9650SE ML12 on last 10 nodes After the upgrade to 1.8.4 we were seeing terrible throughput on the nodes with

We see absolutely dismal performance from Canberra to Perth via Aarnet or Grangenet (gig connections across the country). With standard rsync on a tuned tcp stack, we see about 700k/s. I started playing with the --sockopts and have increased the performance to 1.4M/s which is better, but still way off the pace. There are similar patches for ssh at

Hi, I need to write program to run some results from an experiment. i have the results saved in 2 different files, named "tuesday" and "wednesday" (both located within the same file). when i wrote the program for "tuesday" i had no problem running it, but when i changed the work directory to wednesday i got the "cannot change working directory" message. I

Debian Sarge as fileserver. W2003 as an application server on an HP desktop, only providing services to 3 other machines. A DOS application, whcih of course is not g'teed by MS to run on Terminal Server, but has seemed OK. Now it produces extreme slowdowns, I think unpredictably. It seemed to start suddenly last week, raising the question of an MS update that has altered behaviour...

Rails instances themselves are almost always single-threaded, whereas Mongrel, and it''s acceptor, are multithreaded. In a situation with long-running Rails pages this presents a problem for mod_proxy_balancer. If num_processors is greater than 1 ( default: 950 ), then Mongrel will gladly accept incoming requests and queue them if its rails instance is currently busy. So even

I''ve been having great "fun" testing the new (Puppetised) build end-to-end for several days now. The majority of the fun has been coming from vendor packages (no names mentioned), typically with conflicting permissions on files, or perhaps different home directories, UIDs for the app users so it matters in which order you do things in. My current methodology is to go through

Hi, I was wondering if this is normal or if it something i need to wonder about. I get Monit alerts that my mongrels PID files have changed.

I am trying to create a proxy which I can route my browser requests through in order to gather information on the web page loading. At this time I am particularly interested in the many GET requests associated with loading a single web page. Note: This does not have anything to do with rails, my goal is to run a ruby app in the background, set firefox to proxy all requests through it, log those

Hi all, I''m messing around with has_many, and has_many :through (on edge rails), using a join model. Branches and Projects join through ProjectsAtBranches. If I do @branch.projects, I can see the associated projects, and visa-versa, if I manually put them in the join table. But I cannot do @branch.projects << Branch.find(blah), or @branch.projects.clear, and then save the

Hi, Thanks Zed - this is very interesting. One item in particular caught my eye: Does anyone on this list have any comments or validation that Rails 1.2.1 is 2-4 times as slow as Rails 1.1.6? Topfunky provided a link that purports what looks like really horrible performance and memory characteristics for Rails 1.2.1, even v. 1.1.6:

Hi All, I am new to the mongrel mailing list and I have a question (and I didn''t find any answer in the archives). I have successfully installed the apache2.2 proxy balancer with mongrel cluster and that works just fine. For a single rails app I have started 2 mongrels which consume about 100M (ps says 5.0% for each and I have 1G RAM). It seems a bit much but OK. However that would
