Re: Xquartz random crashes today, version 1.2a8, crash log included (now using 1.2a11)



With the new debug mechanism which now writes to the user's home directory, is there anything which can be added to better help find out where these types of rootless crashes are happening in more detailed manner than the crash logs?

Ben, this is probably an obvious question, but is the rootless code that is specific to OS X new/updated in Leopard from what was in Tiger?  Is the rootless code specific to the X version/implementation or is this a general OS X mechanism outside of X?

Guys,

 
I have still been experiencing many crashes even with the latest version, 1.2a11.  The X session will be stable for some period of time, some times several hours, but once the initial crash occurs, it will continue to crash over and over even after closing X and restarting many times.  Each crash that occurs, produces this output at the terminal:

 
"X connection to /tmp/launch-xr9TuM/:0 broken (explicit kill or server shutdown)."

 
The /tmp location will vary, I think, but I always receive this message.  Hopefully that helps point to something.

 
I am including some of my crash logs from today in a zip.  Maybe they will offer some insights.  I sometimes wonder if copy and paste operations inside the X rdesktop window initiate the crashes.  What puzzles me is that fact that once the crashes start, they continue even with new X sessions.

 
Here is the command I am using (and used in Tiger) to start rdesktop:

 
rdesktop -a 16 -g 1600x1000 1.2.3.4 &

 
Please let me know if anything else from me would help. 

 
Thanks,
Jesse
