CHECK WHAT I'M USING WITH PECL: (i just work with one memcache server)
it removed all wrong return from pecl library, since it's don't return
sometimes and i retry again, if the status of servers are ok and i
didn't get any return it's because i don't have anything to get

So we're having rare (maybe a dozen errors per multiple billion
requests) errors with the PECL memcached client. The server failed
callback is fired, but the server in question is up, has lots of open
connections, etc etc. Other clients, like our custom PHP client,
aren't showing any errors whatsoever.
Others at the hackathon mentioned similar issues, again only at large
scale.
Since the failback callback only accepts host/port and not other
useful data like an error message or even the command that was issued,
it's been hard to debug and reproduce in a fixable manner.
But I'd be all over it if someone could help me track it down. :)
Thanks!

Hi, pecl/memcache is maintained and the new NON_BLOCKING_IO branch
adds many new features, one of which is more specific error messages.
Other features include UDP support, pipelining and consistent
hashing. But yes, during the summer not much work has been done so
help with stabilizing the new branch and addressing bugs that crop up
would be welcome. //Mikael On Wed Aug 22 11:46 , dormando sent: >-
