Memcache connection errors

[Kamran Nisar]

umm...
$mc = new Memcache;
if (!$mc->connect('127.0.0.1',11212)) { $mc->connect('127.0.0.1',11212); }
this would incur a loooot of lag for the client if the connection times
out.. and since i am getting this error very frequently...

umm steven.. when u had similar problems.. what did u do to trace the
source.. with some concrete proof that would satisfy the management.. .. i
hope u undertsand.. ;)

and did u experiance any improvement/changes with respect to the problem.,
between different versions.. if u ever switched forth between them...

another interesting thing that one of the devs told me was they when they
used pconnect() they would get connection time out errors and when they used
connect(), they would get the unknown error.....
