I don’t think this is an issue with CB but I think you may be able to help me identify the issue. I am using CB-server v2.2 (also tested on v3.0.3) and as the memcached server for php sessions. During traffic spikes I am noticing the php function session_write_close() is unable to connect to memcached at what seems random. The only variable is the traffic spike. Would this be a linux server limitation or would there be a setting I can tweak in CB to work around this?
