jsrs Error: context pool full after sc_master_value update

I have a main application and a detail application.
Some fields in main application are update from detail, but in two of them I get the error: context pool full
I’ve checked all the fields as well as the variables used, but I don’t see any difference between them
The code is:
sc_master_value(‘idnivelriesgo_conf’,$vidnivelries go_conf);
sc_master_value(‘idnivelriesgo_integ’,$vidnivelrie sgo_integ);
sc_master_value(‘idnivelriesgo_disp’,$vidnivelries go_disp);
sc_master_value(‘idnivelriesgo_auten’,$vidnivelrie sgo_auten); //This gets error
sc_master_value(‘idnivelriesgo_trazab’,$vidnivelri esgo_trazab); //This gets error

any idea?

thanks and regards
