You have been subscribed to a public bug by Jamie Strandboge (jdstrand):
[IMPACT]
* Current gmond crashes when an NFS mount is active due to stack corruption detection complaining about |
sscanf(procline, "%s %s %s %s ", device, mount, type, mode);| when used with too small buffers.
* Fixed three years ago upstream (https://github.com/ganglia/monitor-
core/commit/883f169353bdd58df10f21fb4e78541f53bc0f17).
* Red Hat already backported a fix a year ago
(https://bugzilla.redhat.com/show_bug.cgi?id=689483).
[TESTCASE]
* Make sure the ganglia moddisk.so module is loaded.
* Use NFS for some disk mount
* Start gmond (`gmond -f`)
* Ensure no crash for "stack smashing detected"
[Regression Potential]
* None known...

What I expected to happen: gmond should stay running regardless of
whether I mount an NFS mount
What actually happened: gmond crashes when the system has an NFS mount
active.
It looks like a manifestation of this behavior:

developers at lists.sourceforge.net/msg05118.html
With NFS mount:
root at mymachine# /usr/sbin/gmond -f -c /etc/ganglia/gmond.conf
*** stack smashing detected ***: /usr/sbin/gmond terminated
