Its not only on arm, its also on i386[2]:
JTFR, I tried running the tests on a arm64 porter box, and I get the failure within a few seconds:
$ /bin/bash test-example
Running iva in test mode...
Copied input test files into here: /tmp/tmp.3MwLHzYtUY/test
Current working directory: /tmp/tmp.3MwLHzYtUY/test
Running iva on the test data with the command:
/usr/bin/iva --threads 1 --trimmomatic /usr/share/java/trimmomatic.jar --pcr_primers hiv_pcr_primers.fa -f reads_1.fq.gz -r reads_2.fq.gz iva.out
The following command failed with exit code 1
/usr/bin/iva --threads 1 --trimmomatic /usr/share/java/trimmomatic.jar --pcr_primers hiv_pcr_primers.fa -f reads_1.fq.gz -r reads_2.fq.gz iva.out
The output was:
The following command failed with exit code 139
bash run_kmc.sh
The output was:
run_kmc.sh: line 2: 10022 Segmentation fault kmc -fa -m4 -k95 -sf1 -ci25 -cs1000000 -cx1000000 /tmp/tmp.3MwLHzYtUY/test/iva.out/tmp.common_kmers.zu2h8c0q/reads.fa kmc_out $PWD > /dev/null
On checking the ram consumption:
$ free -h
total used free shared buff/cache available
Mem: 11Gi 622Mi 281Mi 60Mi 10Gi 10Gi
Swap: 15Gi 82Mi 15Gi
Looking at this, it does not _feel_ like a RAM issue - maybe it is something else.
