    Default /var/log/gdm/:0.log ate my hard-drive: Mesa 7.6 implementation error

    The gdm :0.log filled up my entire root partition. Incredibly, Linux continued to run!

    Examined the log and noticed several thousand (million?) occurrences of the following message sequence:

    Code:
    Mesa 7.6 implementation error: bad datatype in interpolate_int_colors
    Please report at bugzilla.freedesktop.org
    Mesa 7.6 implementation error: Invalid datatype in _mesa_convert_colors
    Please report at bugzilla.freedesktop.org
    I suspect that something may be wrong with Mesa 7.6.

    I'm running OpenSuSE 11.2, 2.6.31.14-0.6, with xfce 4.6.1. /usr/sbin/gdm is dated 2010-09-15 17:12.

    did you report the bug? (posting to here does nothing toward resolving
    the bug..)

    No. It has only occurred three times so far (in the span of a week). I'm waiting for it to occur again, so that I can figure out what may be causing it (by a process of elimination).

    I don't like to clutter up the bug reports with unsubstantiated problems. (Better to clutter up the forums!)

    Default SOLVED? /var/log/gdm/:0.log ate my hard-drive: Mesa 7.6 implementationerror

    I think I found the offending program: the voronoi screen-saver.

    I wrote a bash script that monitors the log size and dumps a ps, fuser, and ls output whenver the log grows.

    The fuser, unfortunately, was not helpful -- it indicated only that the log was being accessed by Xorg. The ps output was helpful, however. It told me that the voronoi screen-saver was running at the time -- and not much else. I ran voronoi twice in preview mode and reproduced the problem both times, each time within five minutes.

    I captured the bug in voronoi! -- and fed it to bugzilla!

    thank you!

    in (about) 2001 or so i was having occasional lockups and was advised
    to NOT run random screen savers...

    i have not since..

    along the way i think i've learned that while voronoi might kill yours
    it might not harm my system at all...nasty stuff inside those many
    modules..
