 * I added Batcache was running fine on a few pages then stopped working (showing
   the cache status before head). Memcache server was up so no issues there. Also
   started filling logs with segfaults. I removed Batcache and segfaults disappeared.
   Anyone else experience this?

 * I have the same problem here. I figured that it will happen when I try to open
   any subdomain that doesn’t exist on my wordpress network.
 * Lets say I have a.example.com b.example.co and c.example.co set up if I try to
   access anything.example.com beside those a/b/c I get a white page on the browser
   and in the Apache’s log:
 * [notice] child pid 18019 exit signal Segmentation fault (11)
    zend_mm_heap corrupted
 * That won’t happen if I am logged in the backend. I basically don’t get any response
   from apache and I am not sure what to do in order to troubleshoot that… I tried
   pretty much everything here…
 * Does anyone have a clue?
 * Thanks!

 * I ran a backtrace on a apache’s core dump and I figured that the problem was 
   with pecl memcache php module that I was running. I just installed the latest
   version and the segment faults stopped.
 * Here is what I have now: CentOS Base Php 5.3.3 and memcache-3.0.6.tgz from: [http://pecl.php.net/package/memcache](http://pecl.php.net/package/memcache)
