Hello,

I am trying to create an index from unitigs that I downloaded from Logan. I am working with a total of 837 datasets in the form of unitigs.fa files.

I successfully generated the index using 30 datasets as a test. However, when I attempt to index all 837 datasets, I encounter two issues:

Segmentation Fault with Multiple Threads:
When I try to use multiple threads for the indexing process, I consistently receive a segmentation fault error.
zstr::Exception on Single Thread:
When I reduce the process to a single thread, the process starts but eventually fails with the following error after some time:
terminate called after throwing an instance of 'zstr::Exception'
what(): zlib: Z_DATA_ERROR: invalid stored block lengths

I am wondering if this error is related to a specific dataset or if there might be another issue at play.

Thank you for your help !
