I have a galaxy/cloudman cluster where I would like to pass a "-l mem_free=16G" parameter when galaxy submits the job to SGE. I've tried adding it like this:

default_cluster_job_runner = drmaa://-l mem_free=16G/

(it was:
default_cluster_job_runner = drmaa:///
)

but now the jobs don't even submit. Am I wiping out other important parameters? How should I do this?

Thanks,
Jim
