In this case this is considered a transient error with no affection. If you still see the errors showing, in a secure window (Maintenance Window) try reinserting the affected sib and the errors should correct themselves.

This is a transient issue and no impact is reported. Logs should selfcorrect, however, if the messages are still seen, a reboot should clear the errors, if still needed, a reseat should be enough for resolution; this workaround should be performed during a secure window (Maintenance Window).
No replacement is needed in first occurance.

Note: if still required, please contact Juniper Networks for further assistance and investigation.
