"Incomplete response received from application" message

I have recently migrated rails projects to Yosemite, I used Rails 4.2.1, Passenger 5.0.6, Apache 2.4.10.
I got page with “Incomplete response received from application” randomly, when I refresh, the app
seems to work and get answer what I want.

I searched around, tried “rake secret” and copy the secrect_key to secrets.yml, but doesn’t seem to
stop the issue. Any advice? My configure file is:

Not helpful, but I too am experiencing this behavior on a new app/deploy on a server where other Rails apps are running fine.

This is happening on a CentOS box in my case. I do not get past this screen even upon refresh. I have a much simpler setup:

<VirtualHost 198.101.243.210:80>

I have three apps, two calls Fortran codes, one doesn’t. The one don’t has no issue, the
two calls Fortran have this issue, but I have installed the same apps (without changing
any code) in Mavericks and they run fine…

I like to attach apache error log (how?), hope someone might be able to detect something?

Post it here: https://gist.github.com/

That said, I'd make sure your unit tests cover the failing area fully
and that they run successfully first.

HTH,

I used the web applet 10 times, the error shows up once, seems pretty random and
there is no problem in several old versions of Ruby On Rails and I didn’t change any
part of Fortran or Ruby codes. I have done debugging Fortran codes,
but couldn’t find any misuse of array, memory allocation and memory deallocation.

The error_log is posted:

https://gist.github.com/Liz-Huang/f6eb0ef4e5b99c62c67b

It seems that the bug is not with Fortran code, I have turned debug on in Fortran code and it runs fine
(actually I tried to test run for 1000 times), it ran in previous versions of Ruby On Rails…

The new error message:
