Hi again!
I'm diving inside DirectUpdateHandler2 code and it seems that the problem
is that when a commit, when core.openNewSercher(true,true) is called it
returns a RefCounted with a new searcher reference that
points to an old (probably cached somehow) data dir. I've tried with
core.openNewSearc
I've seen that StandardDirectoryReader appears in the commit logs. Maybe
this DirectoryReader type is caching somehow the old segments in SolrB and
SolrC even if they have been commited previosly. If that's true, does exist
any other DirectoyReader type (I don't know, SimpleDirectoryReader or
FSDir
