I updated NCPA to 3.2.0-1 on Oracle Linux 9 servers. I am now seeing errors in /var/log/messages:

It looks like NCPA starts and is functioning, but those errors continually repeat and are filling up the log.

Hi @marchiom,

Thank you for the report. I put this into issue tracking on the NCPA repo on github at https://github.com/NagiosEnterprises/ncpa/issues/1291

Okay great. I will track it over on Github as well.

We are also seeing this on Ubuntu and Debian servers.

Hello everyone,

I found some leads on this and hope to have a fix out in NCPA 3.2.1 or 3.2.2. Thank you for your patience.

Hello,
Just seeing to see if this is still planning to be addressed in the 3.2.1 or 3.2.2 deployment? Its still an ongoing issue.
Thanks!

We have a dev on this currently.

Just checking in on this issue. We are still seeing the errors in our logs. If there is some code I can test to see if it it resolves the issue, please let me know.

Hello everyone,

We have released NCPA v3.2.1. This release mostly addresses build related issues, but we believe some of those problems were indirectly related to the NCPA error messages that users have been seeing in their log files. The new release should stop the python error messages from appearing in the system log files.
