Right now we're usig PECL/memcache, not PECL/memcached. p/memcached is based in libmemcached but AFAIK p/memcache isn't. We're using p/memcache because last time I checked p/memcached didn't have a session handler (we're load-balancing the app servers and want to store sessions in memcached) but it seems more recent releases do have it. As for spymemcached, we're using a git version from January. It was a 1.5-pre-something, definitely post 1.4.x but not the final 1.5 release. Maybe the version we're using still didn't had that bug you mention fixed. Will try with pecl/memcached and spymemcached-1.5. > With only two servers, nearly anything could make it be 50% off but it almost > sounds like one client is seeing one of the servers as down.

Both servers were up during my tests, the two of them received both reads and writes. > Sorry I don't have any clear answers here, but I can say it's been tested and > SHOULD work. No clear answers but at least now I know that spymemcached and libmemcached have been thoroughly tested and they should match, so if they're not matching for us we either are doing something wrong or are not using the correct releases. :-) Thanks Matt :-) -- Vicente Aguilar <[email protected]> | http://www.bisente.com
