Suddenly a Blank Page

Rails
1

This is apache/fcgi/rails/firefox.

When using a rails app we have been experiencing sudden blank pages in
the browser.

We show an model “new object” page and start changing stuff and all of a
sudden the page will be erased to blank!

Any idea what could cause something like this?

I experienced the same when I was trying to call a partial that did not
exist.

If you’re running WEBrick, try to remove the ruby session files in /tmp.

Removing the session files worked for me…I had to
do it after switching versions and port for mysql.
Presumably old connection info was in sesion files.

I saw this when switching to DB driven sessions in the environment.rb.
It worked for a while and then all of a sudden, everything was blank. I
turned it off for the moment (back to /tmp) and it is all good. Sorry,
no solution.

Today, I had a problem with sessions that caused that problem. The
session table you can create with rake will use a TEXT column for data,
this tops out at 64KB. I changed this to LONGTEXT and the problem went
away.

Do the pages remain blank, or do they work after reloading? I have this
problem on ruby-forum.com (using memcached sessions).

Once they are reloaded they work fine.

More info: This usually happens while data is being entered into one
particular page (the page that is used most often in the app). You will
be entering data normally then BAM a blank page. Weird

We’ve seen behaviour in development mode where an application using
DB-backed sessions will suddenly fail because it tries to revert to
pstore sessions - production mode fixes this though. This behaviour
was also in Rails of yore, so it might’ve been fixed, but the
description matches what you’ve got, Fredrik.

When this happens I can move to a different page and then back and
everything seems to be ok then.
