I’m getting Input/Output errors on various views in a production app  
we’re running on Webrick on OS X Server - Apache frontend. It happens  
in various places, which makes it hard to track down, and I’m fairly  
certain it’s not my code that is causing the issue.

One example of where the error is thrown is on a page that uses the  
start\_form\_tag as such:  
\<%= start\_form\_tag ( { :controller =\> “validation”, :action =\> ‘cancel’  
}, { :name =\> ‘cancelValidation’ } ) %\>

Nothing special there, the error says  
“Input/output error  
On line #165 of app/views/layouts/reference.rhtml”

#{RAILS\_ROOT}/app/views/layouts/reference.rhtml:165:in `write’

There is no direct call to a “write” method (not on my part anyway).

I’ve read that this may have something to do with rails writing to  
stderr, stdout, but I’m unsure of how to change where it writes to, and  
was hoping others had encountered this before? Could it be in writing  
to the production log? Our production log is 55MB…not sure if that  
could cause the issue…

Thanks
