Hi Keita, I agree. It's most likely running out of space in node-local storage. In fact, I think the error is coming from the test_api code which only writes to node local storage. Is it failing on the first checkpoint? Do you have SCR configured to write to /tmp, and if so, can you check the size of /tmp on your compute nodes? For example, login into a compute node and run "df /tmp". -Adam Kathryn Mohror wrote: >Hi Keita, > >Sorry for the delay. I am not sure why that would be happening.

However 8 MB seems a bit small to be causing that problem.
