DOTS – “An error occurred while processing the command”

If you are using DOTS in Domino 12.x, you might have seen some NullPointer Exceptions after you have updated a DOTS plugin. Recommendation was to delete the complete workspace-dots folder prior to starting DOTS after the upgrade. This issue has been addressed in SPR# SJAAC3BNWV: DOTS – Workspace need to be deleted on every change and add of new plugin. With this fix it is no longer necessary to delete the workspace-dots folder. Not sure, when the fix was provided. There is no information about it in the fix list database. But this is only true for Domino on WINDOWS. If you are using DOTS with Domino on LINUX, you will see an error on the Domino server console ( “An error occurred while processing the command”) or even worse, the NullPointer Exceptions. The problem is that the underlying API in Domino does not delete files starting with a dot. (hidden files on UNIX systems).

A few days ago, a customer reported that one of our applications was not working properly and sent the associated logs. It was very quickly clear under what conditions the error occurred. So it was reproducible, which is the first important step to troubleshooting. Nevertheless, it took some time to locate the cause. Finally, I was able to find the “error”. To send it ahead. The “error” is not limited to a specific Domino version. The problem also occurs under Domino 9.0.1 FP10.
