[R-sig-Geo] cokriging question

[Dave Depew]

Is there a limit to the # of observations or size of file that can be 
co-kriged in gstat?
I have a ~12000 observation data set (2 variables), the variograms, 
cross variogram and lmc are fit well, and co-kriging starts ok

Linear Model of Coregionalization found. Good.
[using ordinary cokriging]

then immediately outputs

"memory.c", line 57: can't allocate memory in function m_get()
Error in predict.gstat(fit.ck, newdata = EcoSAV.grid, maxdist = 100) :
  m_get

Iv tried different maxdist from 10 to 1000, with exactly the same result.
I recently upgraded my RAM to 4Gb and flipped the windows XP /3GB switch.
