Uncaught exception 'CouchbaseException' with message 'Client-Side timeout exceeded for operation. Inspect network conditions or increase the timeout'

What is the reason behind this exception? How can it be resolved.

PHP Fatal error: Uncaught exception ‘CouchbaseException’ with message ‘Client-Side timeout exceeded for operation. Inspect network conditions or increase the timeout’ in [CouchbaseNative]/CouchbaseBucket.class.php:196
Stack trace:
#0 [CouchbaseNative]/CouchbaseBucket.class.php(196): _CouchbaseBucket->get(‘rm::u:guest_353…’, Array)
#1 /home/octro/vikas/test/TRTC_user/BringUser.php(229): CouchbaseBucket->get(‘rm::u:guest_353…’)

It means the operation could not be completed within the designated timeframe (default: 2.5 seconds).

The reasons might be a slow server or network.

But how to speed-up the couchbase servers to handle such cases? I tried exceeding the timeout period upto 10 seconds, but no improvement.

How did you try doing that? In any event you should ensure the network is quick enough and the cluster is not experiencing any issues. You can enable logging (http://docs.couchbase.com/developer/c-2.4/logging.html and see what happens.

It might also be that you have a firewall blocking your connection, or one of the hosts is unreachable, etc. etc. – are you getting this error during initial connection? or just when you try to do operations?
