Summary: Bug in check_mrtg plug-in

Initial Comment:
I get a segmentation fault when I run the check_mrtg
plugin on Red Hat Linux Enterprise 4.  The plug-in
version is 1.4.2.

I poked into the code of the plug-in and noticed this line:

int expire_minutes = 0;

I changed it to:

int expire_minutes = -1;

I recompiled the code and the segementation fault was
corrected.

Thanks for your reply James,

it has really long time gone.
Is anyone of the devs running a rhel4 server with mrtg to check this?
If there are any other bugs concerning rhel4, i'll probably set up a
vmware image.
If not, i'll close it in the next days.

Again, thanks for your report.

Doesn't seem to but I only have RHEL 5 to test it on - may behave
differently on RHEL 4.  I know it's odd - I have no idea why the change
impacted it either - but it worked after that change.  I could find nothing
else in the compile environment to explain it working.  I am trying to rack
my brains as to what triggered me to change expire_minutes but *shrugs* it
was over a year ago.

Hi James,

could you please tell us if this problem persists in the latest version
(1.4.9 or cvs snapshot)? If so, we need the command line you used (i guess
verbose output isn't possible with check_mrtg).
I watched the source and can, up to now, hardly imagine how setting
expire_minutes to -1 can prevent the plugin from segfaulting. We'll see..

Matthias
