Memcache :: set () broken pipe

Question

In general, Memcache works ... but my log has many entries in this:

Memcache :: set () [memcache.set]: send from 8192 bytes with error = 32 Broken pipe

(number of byte changes)

PHP5.3, Memcache class (v2.2.5 - latest stable version )

What is a broken pipe, why is it so much, and can it be improved?

Answer 3

Generally speaking, when I see Broken Pipe errors, this happens at an extremely high load. Is this the matter with you? In some cases, simply adjusting the settings may solve the problem. If you allow more connections to something than something that can handle it, you'll often get an interrupt error message.
