[SIESTA-L] error when generate the O2- Pseudopotential

[Fen Hong]

Dear all
 I want to get the O2- Pseudopotential, valence orbital is 2s2 2p6.
There still has error in the output while it worked when I tried the 2s2 2p5
3d1.
Does anybody know the reason?
the input is
   pg      Oxygen
        tm2  2.0
 n=O  c=pb
       0.0       0.0       0.0       0.0       0.0       0.0
    1    4
    2    0     2.00      0.00
    2    1     6.00      0.00

      1.15      1.15      1.15      1.15

error :
error in pseud2 - nonconvergence in finding
 starting delta for angular momentum 0
stop parameter =821
