When requesting memcache, libmemcache gives "CONNECTION FAILURE", how to solve?

Question

Zend Framework

Hello.
In some cases I get "CONNECTION FAILURE" when I try to ask/put something in the cache. In all respects, these cases are no different from successful requests.
Can you suggest where to dig? Or if you met with a similar one, how did you decide?

Answer 1

Look for logs, system logs, PHP logs. Or try to include more verbosity for the logs. I have no idea what you have in this case, but when you find a more detailed description of the problem, you will understand what the problem is

Answer 2

I faced the same problem, 1/3 of all memcached requests fell off, as a result, I switched to redis just a week ago, the problem is gone.
