Answer 1

I encountered this error recently. Apache was not able to write to tmp directory

cannot generate tempfile /tmp/RackRewindableInput2xxxxxxxxxxxxxxxxx' /app-lib/lib/ruby/1.8/tempfile.rb:52:ininitialize' app-dir/vendor/gems/rack-1.0.1/lib/rack/rewindable_input.rb:73:in new' app-dir/vendor/gems/rack-1.0.1/lib/rack/rewindable_input.rb:73:inmake_rewindable' app-dir/vendor/gems/rack-1.0.1/lib/rack/rewindable_input.rb:26:in read' app-dir/vendor/gems/rack-1.0.1/lib/rack/request.rb:134:inPOST'

I checked permission of tmp directory and it had permission to all groups to write to it. I changed owner of tmp directory and it didn't resolve the error either.

The culprit was tmp directory was filled with too many large files, and looks like somehow apache didn't had enough space to write this new file. Cleared all temp and old files. It sorted out the issue.
