Openbox (OB) window manager (started by xinitrc as openbox-session) with 'conky &' in the OB's autostart file. Standard setup (according to all sources).
All starts up fine.
On exiting OB, xinit connection to xserver is lost so X starts to close
but it gets troubled by conky ( as when conky is not running, this does not happen) and reports :
waiting for X server to shut down XIO: fatal IO error 4 (Interrupted system call) on X server ":0"
after 1499 requests (1499 known processed) with 3 events remaining.
(EE) Server terminated successfully (0). Closing log file.
It as if X cannot 'talk' to conky to get it to close.
Now it may not be catastrophic, but do any experienced conky users know what this problem is and how to fix it please?
