Wasn't sure where to ask about this. I wasn't able to find anything about it on google will appreciate your help.
I am using the ruby SDK
I have a cluster with two nodes.
I am able to connect to bucket but when ever I set/get a document the process segfaults
Similar issue has been reported here: http://www.couchbase.com/issues/browse/CCBC-254
There is a bug in libcouchbase 2.1.1, it has been fixed and accessible in master branch (will be released in couple of weeks)
As workaround you can set bucket password, and specify bucket/username/password during connection (where username is bucket name)
