Comment 6 Lakshmi 2018-09-05 18:36:34 UTC
Four months ago this issue used to occur frequently and disappeared. Again this issue appeared two months ago (didn't occur for 42 rounds in between). 

In all the cases this issue happened to appear only with drmtip rounds. 

This can not be closed until we don't have failures at least for the next 2 months. Priority is changed to medium.
Comment 7 Lakshmi 2018-10-19 12:33:02 UTC
This issue occurred last time with drmtip_61 (4 months, 1 week / 2264 runs ago).
I assume this issue was fixed, closing this issue.
