I have been noticing random failures for test 004_basic_sanity.check_snapshot_with_memory

The failure is not connected directly to any of the failed changes and its either a problem with the test or a problem in vdsm which is causing the failure of this test randomly.

the error we are getting is:

Fault reason is "Operation Failed". Fault detail is "[Cannot run VM. Low disk space on Storage Domain iscsi.]". HTTP response code is 409.

I think that its related the sparsify failure we have seen in the past [1] but it has been happening more often now. 

Tal, can someone in your team review this again? I think that if this is not resolved soon I will skip the test

so that it does not fail changes for no reason. 

You can see failed build here:
