GenomicsDBImport bus error
I am a new user for gatk4. Recently I tried to combine 800 g.vcf files. It is quite slow by directly use 'CombineGVCFs', so I tried to use 'GenomicsDB' to make cobimed db file first. While after running few day, I just check the log file it is showd '3410 Bus error', what's the meaning of this error and how to solve it?
By the way, I want know is there any better method to combine g.vcf files more faster?
