[c-nsp] INAC PVC?

I have one of 1698 VCs on my 7206 VXR NPE-G1 that shows "INAC".

Here come all the diagnostics I know how to gather on this:

router-7204#show atm pvc 2/263

VC 2/263 doesn't exist on 1 of 1 ATM interface(s)
router-7204#show atm pvc jgoodwin     

router-7204#show atm pvc | include jgoodwin
1/0.8      jgoodwin       2   263  PVC    SNAP     UBR    1536              INAC
router-7204#show atm class-links 2/263
router-7204#show atm class-links jgoodwin

 !
 pvc xtaxxor 2/264 
  class-vc pppoe1536
 !
 pvc xcarlxn 2/314 
  class-vc pppoe3072
 !

Obviously, the DSL customer on that VC is not working.

When we tried to add the PVC, because we couldn't see it with the show
commands. . . .

router-7204#config t  
Enter configuration commands, one per line.  End with CNTL/Z.
router-7204(config)#int atm1/0.8
router-7204(config-subif)#pvc jgoodwin 2/263
router-7204(config-if-atm-vc)#class-vc pppoe1536
router-7204(config-if-atm-vc)#end
Failed to create vc


Try to remove the PVC:

router-7204#config t
Enter configuration commands, one per line.  End with CNTL/Z.
router-7204(config)#int atm1/0.8
router-7204(config-subif)#no pvc jgoodwin 2/263
%ATM: VC was not configured cannot delete.
router-7204(config-subif)#end
router-7204#

Logs show:
3w2d: %ATM-3-FAILCREATEVC: ATM failed to create VC(VCD=1741, VPI=2, VCI=263) on Interface ATM1/0, (Cause of the failure: vpi/vci pair already in use)

I've been googling, but ATM and INAC are not good search terms, way too
many "inactives"...

Does anyone know of a way to fix this without a reboot?  

Does anyone know what might have caused this?

Thanks for your help...
