fatal error: unhandled exception (During Bump Maps) - eepjr24 - 11-23-2020

I am applying quite a few bump maps in my current project (regional map) and get the fatal error about 1 in 6-8 times. The image is kind of large (~86 MB) but most times works fine.

System is Windows 10 Enterprise 64 bit
Gimp 2.10.22. 
25% memory usage with 64 GB Physical ram installed. 
Processor Intel® Core™ i7-8850H CPU @ 2.60GHz, 2592 Mhz, 6 Core(s), 12 Logical Processor(s)

How to diagnostic the memory issue? - Gimphried - 10-17-2021

Hello eepjr24

In order to diagnostic the memory issue:
  1. restart Gimp before each very big bumpmapping
  2. make a clean reboot as you wrote yourself
  3. Gimp menu Windows > Dockable Dialogs > Dashboard as suggested by rich2005
  4. Gimp menu Windows > Dockable Dialogs > Error Console
How to run Gimp for debugging purpose?

Right-click Windows Start > contextually menu Windows Powershell.

Add or not the following Command Line Arguments after the Gimp executable as optional parameters:
. "C:\Program Files\GIMP 2\bin\gimp-2.10.exe" --console-messages --stack-trace-mode=always --no-shm

  ^ Don't forget the Powershell dot operator at the very beginning of the command.  Idea

More precisely, use or not, --step-by-step--, the following Command Line Arguments:
  • --console-messages: Do not popup dialog boxes on errors or warnings. Print the messages on the console instead.
  • --stack-trace-mode=always: Debug in case of a crash
  • --no-shm: Do not use shared memory between GIMP and plugins
  • --no-cpu-accel: Do not use special CPU acceleration functions. Useful for finding or disabling buggy accelerated hardware or functions.
Powershell starts a new black console that will display a lot of GECL warnings even when it works.
At the end of session, after you quit Gimp, you are invited to close the black console:

Before entering any character, save valuable warning messages by Ctrl+C to help to diagnostic the debugging session.
Paste them by Ctrl+V in this forum.
