[4.5.0 - coredump] ndomod core-dump with signal 11/sigv

[Kilvador]

Hi!

Just installed 4.5.0 Nagios Core. I'm using NDOUTILS and compiled ndomod from 4.4.7. CentOS 7.9.
Nagios Core 4.5.0 coredumps with signal 11/sigv.

When commented broker string in nagios.cfg - all is working.

Recompiled NDOUTILS and ndomod, no effect. Working without broker, 11 signal with broker.

Found an issue NagiosEnterprises/ndoutils#63 the same picture for me, no specific compilations options.

Coredumps are in attachements.

Hi @Kilvador, thanks for reaching out. To clarify, when you recompiled the NDOUtils project, did you replace include/nagios-4x with the headers from Nagios Core 4.5.0? If you didn't already take that step, give it a try and let me know if you're still seeing the issue. Otherwise, we're probably looking at early April for the next Core maintenance release, hopefully I'll be able to address it during that.

Made test with 4.4.14. Same conditions and... It's working with the same NDOUTILS, Not recompiled again. Just works and passing data to ndomod.

Again 4.5.0. Same conditions and... Core dump.

Will replace headers from 4.5.0 in NDOUTILS and recompile it again. Tell you here if success or not.

I have very similar problem with mk-livestatus, see https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=277289

Hi @Kilvador - just wanted to follow up and say that I have a couple of weeks where I'm able to dedicate more time to Nagios Core maintenance. Did the previous suggestion help or are you still running into trouble on this?

Hello!

Haven't tested yet. Will do in a couple of days. Now using 4.4.14 Nagios Core version.

Hi there! Just wanted to say I have been having the same issue and verified that if you copy all the header files from nagios-4.5.2 and copy them into the ndoutils include folder, and compile and install, the sigsev fault goes away.

Really happy this worked, been trying to get this working for a week.
