[Limdep Nlogit List] problem with loop

[gholamreza hajargasht]

Dear limdep users
   
  I am trying to run this
   
  proc
  front; lhs=y; rhs=X $
  endproc $
  execute; N=1000; bootstrap=b $    
   
  or
   
  proc
  draw; n=nobs; rep $
  front; lhs=y; rhs=X $
  endproc $
  execute; silent; N=1000 $
   
  for both cases (with my data set) after some iterations, I get the following message and the loop stops
  Error: 315: Stoch. Frontier: OLS residuals have wrong skew. OLS is MLE.
  Error: 498: Skipping 97 repetitions after error flag set.
   
  how can I ignore such iterations or reserve ols estimates and continue the loop? any help is appreciated.
   
  best regards
