Two days ago I suddenly started receiving intermittent blank pages. Immediately
reloading the page led to the expected response. Looking at the error logs of
the past two days I can see loads of the following error:
Use of uninitialized value in concatenation (.) or string at
/usr/local/lib/perl5/site_perl/5.8.8/Catalyst/Engine/FastCGI.pm line 169.
It appears that there just isn't any body data to process.
This error was absolutely non-existent until a few days ago. AFAICT the only
things that have changed since then is the session table now being InnoDB
instead of MyISAM and Rose::HTML::Form has been updated to the latest version
(5.7014).
Due to there being no additional error messages or warnings I don't know how to
debug this. Does anybody here have an idea what could be going wrong? I'm using
Catalyst 5.7010.
Are you using Perlbal in front of FastCGI? Perlbal is prone to deliver
blank pages if the back-end times out. Unfortunately I haven't found
a way to avoid this behavior, but maybe someone on the list can help
out ...
Cheers,
Sebastian
