Title: nagios_cache_file can be written after reducing redundant mem footprint ...

while writing nagios metric cache file, these lines often appear in the httpd logs even after increasing the memory the memory limit to the tunes of a GB. Admittedly, nagios_ganglia.cache is of just 37M file content in comparision.

Allowed memory size of 1073741824 bytes exhausted (tried to allocate 34882418 bytes) in /var/www/html/ganglia/api/metrics_autocomplete.php on line 44,

(btw, I think there should be a memcached driver support for having nagios metric cache even in memcached, that would be too good to.)
