Its become a huge problem and its a terrible chillul Hashem. Personally I think it is the Ravs Achrayis to do something about the talking and if he does nothing its on his head. I know certain shuls where talking is at a minimum and it is thanks to the Ravs of those shuls who make it a point that talking will not be tolerated. Its sad that some people have no feeling for kedushas beis haknesses u beis hamedrash.
