Title: Craft hangs when saving any entry and brings Apache down
ThreadText: # Craft hangs when saving any entry and brings Apache down
  
  (Asked by: username_0 on 2014-11-03)
  
  Everything works fine on my local machine (OSX/MAMP PRO) but on my server (Digital Ocean LAMP stack on Ubuntu) saving an entry brings the whole thing down and I have to restart Apache before the site becomes responsive again. It doesn't seem to time out, it just never completes the save. Oddly, it does actually save the data so when I bring the server back up with `service apache2 restart` the changes are there.
  
  Apache logs look like this:
  
  `zend_mm_heap corrupted
  zend_mm_heap corrupted

  The `zend_mm_heap corrupted` bit looks like it could be something to do with it? I've tried increasing out\_buffering as per [this SO thread](https://stackoverflow.com/questions/2247977/what-does-zend-mm-heap-corrupted-mean) but it didn't help. I don't know where to even start with this, I've never experienced it before.
  
  Apologies if this is a bit vague but this is the only place I can think of to ask — I've contacted P&T too.
  
  EDIT: I've re-installed a new version of Craft in the same place on my server and, although the installation went 'Oops' I can actually log in and save entries so I don't think there's anything fundamentally wrong there.
