Description Michal Jaegermann 2011-02-19 20:34:47 UTC

Description of problem:

After an attempt to use gnome-shell I found "Process /usr/libexec/gnome-settings-daemon was killed by signal 11 (SIGSEGV)" and a core file.  Unfortunately I cannot tell much more as gdb stops with "corefile is truncated: expected core file size >= 37392384, found: 20779008".  No idea why such truncation occured.  There is close to 1 GB of a free disk space on a relevant file system.

Version-Release number of selected component (if applicable):
gnome-settings-daemon-2.91.9-6.fc16.x86_64

How reproducible:
cannot tell

Comment 1 Bastien Nocera 2011-03-16 17:03:17 UTC

The kernel is responsible for dumping the core file, not gnome-settings-daemon itself.

Comment 2 Chuck Ebbert 2011-03-17 06:13:50 UTC

Is there a limit set for the core file size somewhere?

No. On the system in question the core size is set to "unlimited".

Comment 4 Chuck Ebbert 2011-03-20 19:14:16 UTC

Is abrt capturing the core file?

Yes, this core file was captured by abrt.

I have another core from gnome-settings-daemon produced few days later.  If I look at it I see:

Core was generated by `/usr/libexec/gnome-settings-daemon'.
Program terminated with signal 11, Segmentation fault.

and again:

BFD: Warning: /var/spool/abrt/ccpp-1298347914-1715/coredump is truncated: expected core file size >= 45613056, found: 798720.

AFAICS core files produces by other things are not truncated.

Comment 6 Josh Boyer 2012-02-02 17:29:23 UTC

This seems fairly similar to 759213 and there is a lot more information in that bug.  Duping for now.
