Yes, this is wierd. On my server I have 128 megabytes of memory, you seem to  
have 12 megabytes. I reduced my memory limit to 2 megabytes and I haven't  
seen such errors.

Do you have installed some recipes/modules or other local customizations? It  
looks like there are one or more global variables containing more than 12  
megabytes data. If so, you can exclude them from being collected by adding  
something like this in config.php:

  # huge variable is $myvar
  $UnsafeGlobals[] = 'myvar';


Otherwise you can try increasing the memory limit in php.ini if you can: see  
http://www.pmwiki.org/wiki/Cookbook/SystemLimits .
