[Devmon] [hobbit] Re: Devmon causing core dumps

Hi all,

I´m getting a lot of core files because of devmon if_load tests for a cisco
6509.

I´m running xymon4.3.0-beta2, I´ve already tried xymon-4.3.0.-beta2 latest
branch with do_devmon.c revision 6222 with no success.
My rrdtool version is 1.3.9.

This core is generated with the default package from xymon-4.3.0-beta2

Does anyone here is facing the same problem?

Thanks in advance,

Buchan,


The revision 164 do_devmon.c from the devmon svn was working good with
4.2.3

After upgrade to 4.3.0 beta2 the revision 6171 and 6222 ( from xymon svn)
do not work.
Even with the last branch 4.3.0 from the svn I'm having lot of core files
and rrdctl. files?
Do you know why the rrdctl files?

But my question is what changes are really necessary at the revision 164 in
order to work with 4.3.0 ?


The diff is between 164(devmon) and 6222(svn xymon) :
