Hi Hernando,
Item
GP00O2TPYBSOWBL967D0QY0WGFH 1885 you mentioed in your post would be program generated for your transformation. Which you can view from open transformation menubar Extras-> display generated program.
This Program shows all routines (start/field/end) for that transformation.
Have you used any internal tables in routines which you fill in transformations. This internal table might be growing bigger.
Also table space is low this dump can occur. Check table space in Tcode DB02
Try to reactivate transformation using FM mentioned by Krishna. If still error persist it might be code error then
