Hi @sjcalise,
Some users have reported that stalls like this can happen when transparent huge pages are enabled. You can check if transparent huge pages are enabled on your system by running
cat /sys/kernel/mm/transparent_hugepage/enabled
if the output doesn’t contain [never], including the square brackets around ‘never’, then you have transparent huge pages at least partially enabled. If that’s the case, I recommend disabling them. You can do so like this:
echo never | sudo tee /sys/kernel/mm/transparent_hugepage/enabled
Please let us know if this resolves the issue for you, it’s helpful data for us.
