Problems with mod_gearman after upgraded Nagios Core

[bosecorp]

if I disable mod_gearman from nagios.cfg Nagios is able to start.

Here is the error

If you upgrade Core you need to re-upgrade gearman.

I would make backup copies of all you gearman configs (just in case something goes wrong) and run the Server Installation - Upgrade process on page 2

https://assets.nagios.com/downloads/nag ... ios_XI.pdf

[bosecorp]

Yes, I did try that as well and didnt work

What version of Core are you running? And the subject is "Problems with mod_gearman after upgraded Nagios Core"

Did you upgrade Core outside of the Nagios XI upgrade scripts?

This is NOT supported.

Thank you for the information. Due to the nature of some of the enhancements in 4.4.0+ the header files have changed. ModGearman bundles their own Nagios headers and they haven't been updated to account for the recent changes. Not only that, but there will need to be some logic added to ModGearman to allow for adjusting some host related information. I'm working on getting it working for XI/Core users now - and I've opened a ticket upstream to see how they'd like it handled. https://github.com/sni/mod_gearman/issues/136

Thanks again!
