Hello, We recently implemented memcached to keep our database from crashing because of too many connections to it.
Now we have two memcached servers which handle the DB-access and as long as both servers are online we encounter no problems. However when one of the goes down. Half our users loose their sessions. While thats ugly it is actually not the biggest problem. Because if one server goes down users not only get kicked out, but they also struggle to use the site at all. It seems like the apache-client doesn't recognizes that one of the memcached servers went down and still tries to reach that server on every fracking request. The only thing that were changed on the memcached client were the implementation of "memcached.so" in php.ini and changing the [Session]-settings to "session.save_handler memcached" and "session.save_path = memc01, memc02". Can anyone help me to figure out what is going on here, please? Another thing is, that we would prefer to have the exact same data available on both memcached-Servers. So if one of the two can't be reached, the other one is asked. So no user is losing his session when one server suddenly goes down. I already searched a lot and it actually confused me quite a bit (memcache and memcached) and didn't bring up any results for me specially my first problem. Maybe I'm just terrible at googling or to stupid to find the solution. Oh, and please don't feel offended by my probably bad grammar and spelling, while I am listening a reading quite a lot english. I don't write or speak the language often. However, any kind of help is welcome. :) SAE
