error in solve_technical question

Hi everybody,

it's a technical question .

i have a matrix with 30 columns and 40000 rows, 

i start my program and  i found this error:

"error in solve.default(sBB + Z[,,i] %*% Gamma %*% t(Z[,,i])):
system is computationally singular: reciprocal condition number = 
7.6377e-018 "

 is it R limit?


thanks a lot.
