What do you mean 'two Primary Domain Controllers' ?
Do you mean, 'I provisioned a DC and then joined another DC to this',
or did you actually provision two DC's in the same domain ?

Also, please do not refer to them as 'Primary Domain Controllers', a
'PDC' is something else entirely.

No, it is not normal and could be a symptom of your problem.
