AttributeError: 'AsynchronousJobState' object has no attribute 'get_id_tag'

Hi!

We are using pulsar on our cluster with a queued_drmaa configuration (Job scheduler is IBM LSF).
Things are working fine, except on tophat 2 when we want to use mm10 reference genome (sacCer2 is running properly).
We get the AttributeError => `'AsynchronousJobState' object has no attribute 'get_id_tag'`.

As the mm10 reference genome is way bigger than the sacCer2 reference genome, do you think it could be a memory reject from the cluster, resulting in the _AsynchronousJobState_?

Do you know when this error is occuring, and what does it mean for our job? Do you think we could then handle this type of error in a more detailed output to help people debug why Pulsar is returning this?
I can help on this, if needed!

Here are the full log we get in Galaxy:
