Can you attach your X server config file, your X log file, your /var/log/messages file, and the output of: cat /proc/version lspci -vvn lsmod Created attachment 83867 [details]
Requested config files and system logs
Here is requested information about my system (DELL PowerEdge 4600) as an attachment 'phoenix.tar.gz'. Thanks in advance, Boris Mironov email: bmironov The problem in the subject of the bug happened on Nov 1 at 11:45am. After that I've lost ability to use local keyboard and mouse, but telnet sessions were Ok. At noon I've restarted whole system by pressing 'Reset' button. Hope, it will help with system logs. Thanks for the info. One request though... in the future, please attach all files as individual uncompressed file attachments one at a time. That facilitates viewing them easily in a web browser. Changing component to XFree86, as this is not a 3.3.6 bug report. I've looked at your logs, and don't see anything noteable. Not even a sign of an XFree86 crash in your X log. Are you sure this log is from after a crash? If you start up X again after a crash, it will wipe out the log, so you need to snag a copy of the log without starting up X. Also, I'm not sure what you are refering to as the "panel". Is this the GNOME panel? If GNOME is crashing, that isn't an XFree86 bug. I've CC'd a couple of our GNOME guys for comment also. I am not sure that it is exactly XFree86 bug. Probably, it is not (because I
see blue background /*not black and white*/, some elements of desktop, etc...).
Sorry, my mistake.
The XFree86.0.log is exact log that has been written on crush time (Nov 1,
11:49am). Since then I did not start X again.
By "Panel" I refer to Gnome-panel ("with Gnome-logo" foot).
On a side note, separate from the bug report.. You do realize you can use X on a different machine, and run Oracle tools via "ssh -X" remotely, without requiring an X server on the Oracle machine? Just thought I'd mention that in case you weren't aware. It could be a useful workaround for now for you. Owen, Havoc: Any comments? I don't see any XFree86 problem here, but before reassigning to gnome-panel I wanted to get your opinions. TIA Thanks, It is really good idea! But I feel bad about existance of the problem in new production system. ... and posting little yellow note on the rack: "Do not 'startx' on this server or I will fire at will" (just kidding) It's hard to tell here ... the useful file would be ~/.xsession-errors user from the user that you tried in as. It would be also useful to know if you could log in with a different user. Is the 'bigpages' command and starting oracle relevant? If you reboot and don't do that, can you log in OK? If so, then it's almost certainly a kernel or possibly an X bug. Hello again, I was calling RedHat tech support. It seems now as misconfiguration of shm. Probably, this is the cause of the 'segmentation fault' error (shm was configured to be bigger than size of physical memory + swap). For now, I guess, we can close this bug and if problem reappears I will create another one. Thanks a lot, Boris Mironov email: bmironov P.S. Another misconfiguration of my system (regarding to RedHat tech. support) was incorrect kernel. It is recommended to use the 'Enterprise' kernel in the system with 4Gb+ of virtual memory /* not the 'SMP'-kernel */. My system has 4Gb of RAM and 8Gb of swap. You've indicated your system has been misconfigured, and that you've now worked things out, so I'm closing this as NOTABUG. Thanks for providing the updated information. Sounds good! Let's close it as NOTABUG! Thanks a lot, Boris Mironov email: bmironov |
