perfSONAR User Q&A and Other Discussion

[Aaron Brown <>]

Hi,

The regular testing daemon creates those files whenever a test can’t be 
written to esmond, so that it can be retried later. Note, this is different 
from a test just failing. Whether a test fails or succeeds, something gets 
written to esmond.

You should be able to remove them without issue, albeit you’ll lose whatever 
data might have been in there.

Cheers,
Aaron
