high RAM memory usage GATK-2.4-3

I have started GATK-2.4-3 and have noticed that each tools makes use of a lot of RAM memory. I am talking of about 30 GB per run using
-T ReduceReads for some files. I have an initial 400 million reads per input, before marking duplicates.
Is there something different in GATK-2.4-3 in comparison to the previous version?
I didn't this problem when using GATK-2.3-9.
