RID Pool Running Out Of RIDs?

Hello,
I have been trying to track down if AD will add a new pool set to my RID
pool. When I run dcdiag I'm getting the following:

Starting test: RidManager
* Available RID Pool for the Domain is 22174 to 1073741823
* dc1.abc.com is the RID Master
* DsBind with RID Master was successful
* rIDAllocationPool is 19674 to 20173
* rIDNextRID: 10626
* rIDPreviousAllocationPool is 10162 to 10661
* Warning :There is less than 8% available RIDs in the current pool
<------------------------------

Notice that it is telling me I'm getting close to running out of RID's in
the pool. Is there a point where it will release a new pool set for me and
this is normal -or- do I have a problem?

This is my RID FSMO role holder so there isn't an issue with connectivity.

I can't find anything on how this is handled???
 
This also happened to us, but right before we brought a new pdc emulator online. After the dcpromo of the new server, we passed the rid role to the new server, and the problem resolved itself.
 
Do you have a RID master up and running properly? It
should give out a new set of RIDs once you are half way
though what you have. You may want to make sure you have
the RID FSMO up and running and if not seize the role on
one of your DC's

Unfortunately he is the RID Master. But you have answered what I was
looking for, he looks at 50% for more. You wouldn't know where the 50% info
details are. I can't find anything on this.

How about:
RID Pool Allocation and Sizing Changes in Windows 2000 SP4
http://support.microsoft.com/default.aspx?kbid=316201

"Individual domain controllers maintain local RID pools that are
obtained from a global pool on the RID operations master. By default,
RID pools are obtained in increments of 500. Windows 2000 domain
controllers request a new RID when 20 percent of the RID pool remains."

"With Windows 2000 Service Pack 4 (SP4), the threshold at which domain
controllers start to request a new RID pool has been increased to 50%.
For example, a domain controller with the default RID block size of 500
would start to request a new pool when 250 (50 percent of 500) RIDs have
been consumed. A pre-SP4 domain controller with the same RID block size
of 500 would request a new pool when 100 (20 percent) of the default
block of 500 RIDS remain"
