xpra server dies overnight

[Doug Doole]

I've been running xpra 0.2.0 on Ubuntu (11.10 for the server, 11.04 for the client) for the last two days. My client disconnects overnight and on both days, when I attempt to connect the next morning, the client does not attach.

doole@andammo:~$ xpra attach ssh:reorx:1
Connection failed: [Errno 2] No such file or directory
connection lost: empty marker in read queue
Connection lost

I took a look at .xpra/reorx-1.log, but I don't see anything obvious. I have attached both reorx-1.log and reorx-1.log.old.

On the server, I can see the xpra process running:

doole@reorx:~$ ps -ef | grep xpra
doole      915     1 52 Apr26 ?        11:05:18 /usr/bin/python /opt/xpra/bin/xpra start :1

but I am unable to stop it:

doole@reorx:~$ xpra stop :1
Connection failed: [Errno 2] No such file or directory
doole@reorx:~$ xpra stop
Usage: 
        xpra start DISPLAY
        xpra attach [DISPLAY]
        xpra detach [DISPLAY]
        xpra screenshot filename [DISPLAY]
        xpra version [DISPLAY]
        xpra stop [DISPLAY]
        xpra list
        xpra upgrade DISPLAY

xpra: error: cannot find a live server to connect to

So I manually kill the xpra session (kill 915 - process is gone) and restart xpra. When I reconnect from the client, all my windows are still present (so killing xpra didn't wipe out the window manager for some reason) although the windows have all moved to +0+0 on the screen.

In case it matters, my line to start xpra is:

/usr/bin/xpra start :1

I was previously using 0.0.7.34 and did not see this behaviour.

I suspect that you'll need more diagnostics - just let me know what to gather.

The

Connection failed: [Errno 2] No such file or directory

Is a little odd, it means the socket is gone - why is not entirely clear.
Can you check if the xpra process still has it open?

After that, xpra stop will fail, and connect also..

Maybe you could try to strace the process next time this happens to see what it is doing, or just run the server in debug mode (with '-d all') so we can get some diagnostics.
