Subject:Re: Problem with memcached
View as plain text  
I have a result with good value.

I try to search variable for set limit of use for a node but i cant find 
it! (i see it on mysql website but impossible to refind!)

I'd try increasing the number of connections per node as possible.

Thank Andrew.
