Hi Jean,

now I when opening Emacs I am getting this message:

> 
> Warning: desktop file appears to be in use by process with PID 10234.
> Using it may cause conflicts if that process still runs.
> Use desktop file anyway? (y or n) 


> Error running timer ‘rcd-asciidoctor-preview-buffer-as-html’: (text-read-only) [187 times]


I was checking the PID with:

ps -fp 10234

and I am getting this message:

UID        PID  PPID  C STIME TTY          TIME CMD

Interestingly in htop this PID doesn’t show up. I don’t know why.


Is there a way to solve this problem?


Kind regards

Gottfried
