 * We’ll have these posts which get a large number of comments, and finally they
   hit some wall and we get errors like this:
 * [Mon Sep 13 05:05:48 2010] [error] [client 64.236.128.62] PHP Fatal error: Allowed
   memory size of 52428800 bytes exhausted (tried to allocate 275282 bytes) in /
   home/unprofes/www/wp-content/plugins/w3-total-cache/inc/define.php on line 233.
   That line is checking to see if the content is xml or html.
 * That’s fine, I can resize my server to get more space and see what is happening.
   But what’s interesting is I could not figure out what caching method was causing
   this (page cache, database, etc), so I disabled *all* the caching, and I was 
   still getting this message.
 * I ended up having to Deactivate the plugin to make the error message go away.
 * Two things: 1) This seems to be a slightly excessive way to check for xml vs.
   http, by reading the entire string. May be better off grabbing the first chunk
   of data; and 2) Why did I have to deactivate the plugin and not just disable 
   it to make it stop executing part of its code?

 * Did you disable minify? Did you increase PHP memory limit?

 * Hi
 * Minify is disabled. The only options enabled are “Page Cache”, “Object Cache”,
   and “Browser Cache”. In fact, when I get this error, I tried to turn off the 
   other three options, but I still received the error. I had to deactivate the 
   plug-in to make that error stop.
 * As for increasing php memory, I’m working on this.
 * thanks
