Oops forgot you use A7, error() maybe is a A8 feature (search for "error" without quotes).

A few ideas where to look:
- since when do you have this leak? Try remembering the things you have added, especially pointer related and ent_remove / ptr_remove related and array etc.
- check if any pointer you use is not NULL (especially entity, panel and bmap pointers)
- check your arrays if you do not access anything outside of the array's limit/size (e.g. myArray[-1] , silly example I know ).
- check if you dont do anything complicated in your entity events (or if you forgot to do a wait(1); before e.g. doing a c_scan or spawn particles or such in an entity event )
