I have solved it!
I recompiled from source instead of using the binaries and it worked fine.
We have a scientific linux HPC and it seems there was something about that which was causing problems if you ran the precompiled binaries.

Thanks for providing the info. Can you also send us the fastq files so that we can reproduce the problem and find out what went wrong?
Best,
Wei

Hi,
The command I use for subjunc is:
subjunc -i $TMPDIR/hg19 -r $TMPDIR/$2_R1.fastq.gz -R $TMPDIR/$2_R2.fastq.gz -o $1/$2.bam -T 8 --gzFASTQinput --allJunctions

Has anyone seen this before?

Dr. Shi (author of Subread) participates here and we may hear something enlightening from him. But I would have thought that once the genome index is read into memory that requirement should be more or less satisfied. Unless subread works differently (I don't use subread) than other aligners.

Unfortunately not, the disk space assigned to the node is 10TB, the walltime is 5 days (when typically the job takes 2-3 hours) and the temp space is "unlimited" although practically is about 4TB.

Memory does not sound like the culprit here. Are you running into some other limit, say storage (quota) or tmp space or time assigned for job?

The complexity of cancer is clearly demonstrated in the diverse ecosystem of the tumor microenvironment (TME). The TME is made up of numerous cell types and its development begins with the changes that happen during oncogenesis. “Genomic mutations, copy number changes, epigenetic alterations, and alternative gene expression occur to varying degrees within the affected tumor cells,” explained Andrea O’Hara, Ph.D., Strategic Technical Specialist at Azenta. “As...-
