Function iterator optimization

Question

I have implemented a function designed to assign properties to specific components according to predefined rules. However, during execution, the memory usage continuously increases, eventually leading to a software crash. Could you please advise on potential optimization strategies? 
 code ; 
 
 proc parts_NCHandle_event_handle_dsn {} { 
 set lStatus [DboState] 
 set lSession $::DboSession_s_pDboSession 
 DboSession -this $lSession 
 
 set lDesign [ $lSession GetActiveDesign] 
 set NULL_OBJ "NULL"

set lSchematicIter [ $lDesign NewViewsIter $lStatus $::IterDefs_SCHEMATICS ] 
 while {[ set lView [ $lSchematicIter NextView $lStatus ]] != $NULL_OBJ } { 
 set lSchematic [DboViewToDboSchematic $lView ] 
 puts $lSchematic 
 # 
 set lPagesIter [ $lSchematic NewPagesIter $lStatus ] 
 while {[ set lPage [ $lPagesIter NextPage $lStatus ]] != $NULL_OBJ } {

Hi ZH202409115233 ,

Are you monitoring memory usage in Task Manager and noticing it gradually rise to 100%, after which the tool crashes?

Also, does the same script run fine on a smaller design?

If yes, one thing you could try is disabling online DRC while running the script. You can do this by going to:
PCB > Design Rules Check > Options, and turning off online DRC.

Hope this helps!
