kmc stuck at Stage 1: XX%(less than 100%)

Hi,
I am running kmc for ONT reads of fastq.gz. For some accessions, kmc finished without problems. But for some accessions, it stucked at stage 1, uncompleted.

I tried several codes as below:
kmc -t24 -ci2 -k31 accession1.fastq.gz kmc_canon ./
kmc -t16 -ci2 -k31 accession1.fastq.gz kmc_canon ./
kmc -t8 -ci2 -k31 accession1.fastq.gz kmc_canon ./
kmc -t4 -ci2 -k31 accession1.fastq.gz kmc_canon ./
kmc -t24 -m24 -ci2 -k31 accession1.fastq.gz kmc_canon ./
kmc -t24 -m64 -ci2 -k31 accession1.fastq.gz kmc_canon ./
kmc -t24 -m64 -r -ci2 -k31 accession1.fastq.gz kmc_canon ./

None of these worked. What is the possible reasons? And how to solve it?

umm...It only worked if I decompress fastq.gz to .fastq...
