I was running hisat2-build against a very large, multiple sample VCF file. After almost 3 days of running, it finally segfault 'ed...

hisat2-build --large-index -p40 --snp /(snip)/SIDXXX-A.merged.snp  --haplotype /(snip)/SIDXXX-A.merged.haplotype  /(snip)/GRCh38_87.fa /(snip)/SIDXXX-A.merged

Is it possible the indexes are still reliable (I.e. did it segfault AFTER the indexes were complete?...I can't tell fro the output...)

IS it possible to fix this?

I notice that it seems like HiSAT2 may not really be supported anymore by the developer...
