Try many times, sometimes wait 15 seconds.
could you add
ini_set('error_log', 'syslog');
ini_set('couchbase.log_level', 'TRACE');
to your script and show the syslog messages (they should have timestamps)
Or run the script under strace/truss with timestamps, to find out what might be a bottleneck

Lets say you have simple script like this
<?php
$cluster = new Couchbase\Cluster("couchbase://192.168.1.194");
$cluster->openBucket('beer-sample','');
When you run it with strace -ttt php -d extension=.libs/couchbase.so /tmp/test.php you might get the output like this:

At line 110 you might see the library start sending data to port 53 of my DNS server. By default libcouchbase will try to pull DNS SRV records to get the list of cluster nodes, if you don’t need this behaviour, you have to disable it explicitly using dnssrv=false flag in the connection string. DNS SRV feature allows to to delegate managing cluster bootstrap nodes to your IT department, and let all the application nodes use the same address and do not care if the cluster will be moved.
