OrCAD 22.1-2022 P001 [10/6/2022] Windows SPB 64-bit Edition Instability Issues

I haven't faced such issues. Make sure you are meeting min specs requirement

Yes, I experience OrCAD PCB 22.1 s004 every day several times a day, intervals 20mins - 1 hour. The crash happens during manual trace edits of small double sided and 4-layer boards (when moving segments or some other benign editing operations). The RAM is 20GB, Windows shows 14GB free RAM, so it is not RAM. No other application on this machine crashes. I experienced same behavior of SPB 17.4 on all recent releases on a different computer, and hoped that the problem was fixed with Orcad 22.  When PCB editor crashes, it leaves a *.SAV file which contains the latest work, so renaming it to PCB brings back the state immediately before crash. It is annoying, but I continue to struggle because I need the job done. Maybe I am doing too many manual edits. I did not capture the message screen because it quickly disappear, but it says something like "it experienced an internal problem and needs to close".

I think there is S005 available so worth to try.

Can I ask you if orcad create memory dump files? for me it does but they always 0B size.

And please complain to support on every crash. So many people just ignore the crashes so cadence is not doing anything - they just simply not aware about the size of the problem.

Hello Celsiuss, you can try renaming your pcbenv folder. Once you rename this reinvoke the PCB Editor to check. This will create a new pcbenv in your directory.

You can find the pcbenv folder in your HOME folder. To reach to your HOME, type %HOME% in windows run dialog box. 

If you have any SKILL customaizations in your environment, renaming pcbenv will remove them. So to narrow the the issue make sure you only rename this folder and not delete it so that you can go back if required.

If this does not help, open the PCB Editor and go to Setup > User Preferences > Display > OpenGL and enable the variables "disable_opengl" and "disable_gpu". Restart the PCB Editor, you will see very different graphics as these variables disable the effect of graphic card on yur tool. If you see the frequency of the crash is reduced that means the crashes are happening because of graphic crasd in your machine.

Make sure you update the graphic card drivers and then check by disabling these variables.

Also, you can set the Autosave interval such that you does not loose the work and the tool autosave your work at the desired interval.You can read about the autosave in the below forum post:
