We are just trying out couchbase to handle our master-master memcached php-sessions on our 3 servers.

Installations are flawless, and server1 has everything setup and running (sessions bing written to memcached).
But the second I press the 'rebalance' to add another node it all fails and I get:
[25-Sep-2012 14:07:04 UTC] PHP Warning: Unknown: Failed to write session data (memcached). Please verify that the current setting of session.save_path is correct (127.0.0.1:11211) in Unknown on line 0

until the point when I remove the new node and it stops instantly to fail.

I have one bucket 'default' -> 64MB, if I name it anything else I noticed that not even server1 will work alone so default seems right, but why is another node killing my cluster?

Googling, I could see some workarounds for resolving this error

"PHP Warning: Unknown: Failed to write session data (memcached). Please verify that the current setting of session.save_path is correct (127.0.0.1:11211) in Unknown on line 0"
