If I'm correct when I think that a line of
30193 ramon 16 0 170M 119M 3628 S 0.0 11.6 0:08.47 Rack: /var/www/salcedoauctions/current
in htop means that there's one spawn of the salcedoauctions app, then how come there are so many more spawns than I've specified?
Here's my httpd.conf:
....
PassengerMaxPoolSize 4
PassengerMaxInstancesPerApp 2
....
Here's the semi-complete htop:

Some notes:
- Yes, I've restarted apache so it can reload the config (several times, in fact, since the server was running out of memory)
- CentOS 5.5
- Ruby EE 1.8.7
- Rails 3.0.1
Passenger 3.0.0
UPDATE #1 Doing
passenger-status
shows the numbers I expect to see though though. I suppose I just understood it wrong. The reason I'm asking is because my 1GB memory is getting used up and sometimes the server grinds to a halt. It seems that those processes are hogging the RAM.- UPDATE #2: I asked around in #rubyonrails and I was asked if any of the apps were forking any processes. Both apps don't fork anything, but I do use Dragonfly to handle my images and attachments. However, I don't know how I can pinpoint if this is the cause of the problem.
- UPDATE #3 (Oct 14, 2011): I upgraded to
Ruby 1.9.2
,Rails 3.1.x
,dragonfly 0.9.3
,ImageMagick 6.7
; and I'm still getting the same problem. It's not Dragonfly anymore because the newer versions don't usermagick
. It does a command line call to convert images.
