xpra processes "stay forever"

[stdedos]

I just updated, and noticed the following on my system

[email protected]:~$ xpra stop all
No xpra sessions found
[email protected]:~$ sudo xpra stop all

Warning: running as root
No xpra sessions found
[email protected]:~$ xpra --version

Please provide more details as per wiki/ReportingBugs, in particular, steps to reproduce. (ie: commands)

I do not get any leftovers on my test systems.

[Antoine Martin]

Your sessions are running as sntentos but you are running xpra stop as root.
This is not meant to work.

[stdedos]

You can notice that I ran this twice: both with and without root

[email protected]:~$ xpra stop all
No xpra sessions found
[email protected]:~$ sudo xpra stop all

Warning: running as root
No xpra sessions found

---

I am not sure of reproducibility, as I lead with "I just updated, and noticed the following on my system". So, apart from having executed sessions shown by ps aux (and having updated xpra), I don't know how this came to be --> and hence, I am not sure what debug would be helpful in this situation. I usually leave the system open for days (or weeks), and I could've collected something if I was asked relatively soon, but I didn't know what :/

Moreover, I haven't seen it since (but server has been running for a week. I could verify, and I don't think anything will come out of it).

[Antoine Martin]

If sessions are not found then their sockets have been cleaned up already, usually with xpra list.
r19571 increases the timeout delay.
