"NoMethodError: undefined method" after switching to unicorn

"NoMethodError: undefined method" after switching to unicorn

[Tiago Scolari]

Hello,
I'm having a lot of "NoMethodError: undefined method" errors after I moved from thin to unicorn.

This seems to happen only with active records, and dynamic methods, like:
find_by_*, scoped_by_*, ...

It seems to be random, at least I haven't found relation yet.
I may reload the same page 10 times, sometimes it will work ok, some times it will give me this error.

I've 2 sites having this issue, one uses rails 3.0.9 (r 1.9.2) and other with 2.3.8 (r 1.8.7).
As i said, the issue started after I switched to unicorn.

Any idea what could cause this?

Are you using preload_app?

Hrm, I wonder if the above file depends on (undocumented) Unicorn internals
that changed in unicorn 4.0.0?

It might be worth it to try unicorn 3.7.0 since 4.0.0 was just released
and some gems that depend on internal implementation details could
be broken.


Maybe somebody else here has a better explanation...

Reverting to 3.7.0 appears to have fixed the issue for the user.

Did you try disabling preload_app?  If that doesn't help, help us
help you by telling us everything you can about your setup,
including (and not limited to):

* Anything that maintains network connections/open files
* All gems and versions you use, including the versions of 3rd party
  libraries (e.g. OpenSSL version)
* OS version
* Ruby version
* CPU architecture
