Combination of ruby-1.9.3-p286, passenger-enterprise 4.0.5 and rvm 1.25.17 creates endless pid spawn

[everestx]

Recently I upgraded to rvm version 1.25.17 from 1.24.8 and I got very erratic behavior. I'm guessing it's related to the use of gem-wrappers in the new version of rvm.

The combination of ruby-1.9.3-p286 and passenger-enterprise 4.0.5 worked just fine with rvm 1.28.4, but with rvm version 1.25.17, passenger appears to spawn child processes indefinitely.

See this snippet from the process listing, where passenger fails to startup a ruby app and eventually crashes apache. Note that this occurred for every child 'httpd' process that the parent 'httpd' process started up.

1. show me your passenger config
2. show the ruby script used and the environment file mentioned in it

gist it if it is longer then few lines

closing as there was no feedback in over 2 weeks, please let me know if you can provide details and I will reopen

Hi there, I totally forgot about your request for feedback. I've created a Gist, which I think gives you what you're asking for. Did I miss anything?

show the /usr/local/rvm/wrappers/ruby-1.9.3-p286/ruby and the environment file mentioned in it

this looks good, the other thing I see here is bash -lc exec, can you run:

rvm get stable --auto-dotfiles --debug

and show me all output (gist it)

[everestx]

This is a pseudo-production host, so can't do it at the moment. I'll get back to you.

[kassi]

I ran into the exact same problem. Here's my gist.

At least for me it looks like it's a permission problem after upgrading rvm (see log).
Now I'm figuring out how to better set the users/permissions.
rvm has been installed as root.

[mpapis]

hmm, maybe try rvm fix-permissions?

[digininja]

that says it set a few permissions but didn't change anything to do with
the rvm get head. The bug is in the script and the way it is calling sed,
not in the installed app, that is why it caused the problem on the very
first install as well as the upgrades.

Has this been fixed? I seem to have run into it with rvm 1.25.26 (stable) and a new install of ruby-2.0.0-p451 .

Him a missing gemset for the newly installed ruby was causing it for me.

[digininja]

It was fixed in the cases where I had a problem.

I assume this is fixed, if anyone else hits such problem please open a new ticket with details of the problem.
