problem with using BWA on usegalaxy.org

I was trying to align 2 fastqsanger files that was trimmed using to FASTQ Quality trimmer (window size 4, average score >=20) to the hg19 reference genome using BWA. But I got the following error message from galaxy job runner:
“slurmstepd: error: _prec_extra: Could not find task_memory_cg, this should never happen”

Command line
set -o | grep -q pipefail && set -o pipefail; bwa aln -t "${GALAXY_SLOTS:-1}" '/galaxy/data/hg19/hg19full/bwa_index_v0.7.10-r789/hg19full.fa' '/galaxy-repl/main/files/038/979/dataset_38979636.dat' > first.sai && bwa aln -t "${GALAXY_SLOTS:-1}" '/galaxy/data/hg19/hg19full/bwa_index_v0.7.10-r789/hg19full.fa' '/galaxy-repl/main/files/038/979/dataset_38979657.dat' > second.sai && bwa sampe '/galaxy/data/hg19/hg19full/bwa_index_v0.7.10-r789/hg19full.fa' first.sai second.sai '/galaxy-repl/main/files/038/979/dataset_38979636.dat' '/galaxy-repl/main/files/038/979/dataset_38979657.dat' | samtools sort -@${GALAXY_SLOTS:-2} -O bam -o '/galaxy-repl/main/files/038/988/dataset_38988929.dat'

Hello
I was about to file a similar problem/topic so no help here just confirming your report.

I too have been getting “slurmstepd: error: _prec_extra: Could not find task_memory_cg, this should never happen” working on usegalaxy.org.

I succesfully mapped a set of Illumina PE reads against a refenence genome in fasta format using BWA-MEM. As from yesterday (04 April 2020) I have failed consistently to filter the resulting bam file using Filter BAM. Initially I was chaining three filters and thought that may contribute.

However subsequent attempt to run a single filter (is mapped or quality > 20) keep failing with the same error:
slurmstepd: error: _prec_extra: Could not find task_memory_cg, this should never happen

The job does partially run as I can see partial results in the centre pane.

p.s. same error if filtering using samtools view
