Aerospike sever has got synchronization bugs :(

Bugs found during VAT testing (http://1307723433353.blogspot.com/2014/05/vat-validation-of-architecture-in-tests.html)

Aerospike is Open Source and if you encounter a problem you can analyze it yourself without waiting for the support in a different timezone. You can recompile fixed code and bring it immediately to the production. It is a way faster than with any platinum level support. You need only one guy who knows Linux and C.
