In general, Memcache is working... but my log has many occurrences of this:
Memcache::set() [memcache.set]: send of 8192 bytes failed with errno=32 Broken pipe
(the number of bytes changes)
PHP5.3, Memcache class (v2.2.5 - the latest stable version)
What is a broken pipe, why is it happening so much, and can it be improved?
