[Solved] xbrlapi zombie process

Post by Terryphi »

System monitor on one of my machines shows a zombie process: xbrlapi. Can anyone suggest what this is a remnant of? I assume this is a program not cleaning up properly.

A remnant of xbrlapi; xbrlapi is accessibility software (braille terminal support).

A zombie process is a process that ran and exited but the parent of which has not collected e.g. the exit status of; a process that "has not been waited on". It's only an entry in the process table, kept around only so that the parent process may check on e.g. exit status; the process as such is long gone. This is to say that nothing's wrong with xbrlapi itself; whatever launched xbrlapi should've waited on it. It is also to say that you should feel quite free to ignore the issue: a zombie does not take up memory or other resources other than that tiny bit of exited-process information; is fully inconsequential.

That said; I don't have the issue on Mint 19 Cinnamon but some googling suggests that'll be your session manager that launched xbrlapi (if you print a process tree with e.g. ps axf on the concerned system you'd be shown such) and it will no doubt do so through /etc/X11/Xsession.d/60xbrlapi. If the zombie still annoys you --- and assuming you don 't in fact need braille-terminal support --- you can rename that file to e.g. /etc/X11/Xsession.d/60xbrlapi.disabled to disable it.
