GenotypeGVCFs Hangs at the start

Hi team, thanks for your work.

I'm currently running GenotypeGVCF on 78 WG individuals using the -L option to run each chromosome separately.

java -jar -Xmx20g -XX:ParallelGCThreads=10 GenomeAnalysisTK.jar 
-T GenotypeGVCFs
-R references/human_g1k_v37_decoy.fasta 
--num_threads 10
--variant [78 WG individuals]
--variant ...
 -L chr10_region.interval

I started running v3.0, but also ran v3.3, with the same issue.


Each time it runs it gets to the same point and then hangs for >18 hours, before I kill the job.

If I'm correct 78 WG individuals should not be an issue.

Any ideas as to what is causing this issue?
