Errors when writing to logs (A Errno::EIO, Input/output erro

Hi,

I’m getting write errors randomly (about 5% of the time) whenever
Rails writes to the production log or caches a page, at first I
thought it was every time it wrote a file but it will happily spit out
95% of cached pages then throw out an error like the one below:

A Errno::EIO occurred in answers#new:

Input/output error - /home/4927/containers/rails/what2tip/current/
config/…/log/production.log
/usr/lib/ruby/1.8/logger.rb:513:in `write’

or

A Errno::EIO occurred in pages#index:

Input/output error - {pathtosite}/current/config/…/public/
index.html
{pathtogems}/rubygems/gems/gems/actionpack-1.13.1/lib/
action_controller/caching.rb:90:in `initialize’

thanks!
