Performance logs did not include the header when rolled. If QVS is configured to roll logs this may be disabled or configured to roll less frequently as a workaround. The root cause is still under investigation as it could not be reproduced in a controlled fashion by Qlik.
Workarounds: 1. Copy the header from another performance logs (or below) and past on the one missing it.

2. If QVS is configured to roll logs this may be disabled as a workaround as well to prevent/minimize the issue recurrence.
