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

[Mario A. P. <row...@gm...>]

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,

Mario.
