Did you regenerate the php thrift bindings between 0.5 and 0.6?  There's a
decent chance that thrift made some kind of backwards incompatible change
between those revisions (look in the lib dir of each cassandra version to
determine the thrift svn revision you need.)  If that happened, then it's
possible the old bindings are sending something the newer version does not
understand, and causing you to run into THRIFT-601, crashing the server.
