I'm using aws ec2 ubuntu and have ssh connection.
All commands entered from ssh connection to s3 produces the error:
Bus error (core dumped)
Originally, I was trying to do a copy from mybucket to the server:
aws s3 cp s3://mybucket ./
but the result was the error. Even an ls command produces the error. I don't know how to fix this.
A few days ago, I expanded the system using these instructions for ebs volume.
The df -h command produces this:

Today, work was proceeding as normal until I entered the command:
grep -vf MergedSamplesEdited.vcf ../resources/plink.GRCh37.autosome.map
The system Killed
the process.
I was then able do a few more grep / awk commands, including the one I should have done instead of the grep line above:
gawk -F$'' 'FNR == NR {a[$6]; next;} {if ($4 in a) {print $0 } }' oldfile.ibd ../resources/plink.GRCh37.autosome.map > newfile.ibd
Needing to copy files from s3 bucket, I tried the aws s3 command above and got the bus error.
I searched for a solution and found responses with the bus error, but those responses seemed highly specific and did not apply to my situation. For example, Git add . Gives me Bus error (core dumped).
Your help would be greatly appreciated.
