issue with adding Mfill

KVBABU

Hi

Iam  working on design with TSMC 28nm technology, in which i tried to add Metal fill . Even with default settings in encounter GUI , i could not able to add Mfill, diplaying below error and warning  messages:
addMetalFill -layer { M1 M2 M3 M4 M5 M6 } -nets { vss vdd } -timingAware off
**ERROR: (ENCMF-192):   Spacing table is too big (width:440 length:440)
End metal filling: cpu:  0:00:00.0,  real:  0:00:00.0,  peak mem:  651.17  megs.
**WARN: (ENCMF-9):      5 memory pool(s) not released!

*** 5 memory pool(s) in use ***

 I could not able guess , from where the tool is picking up the spacing table  (width:440 length:440).
Kindly help me to resolve this issue.
