Error: journal: g_array_unref: assertion 'array' failed

[JJ Smith]

I have a new build of a Centos 7.6.1810 running on server. The server itself seems to be running great, nothing appears to be crashing or going down, but I am getting the following error message in my logs:

journal: g_array_unref: assertion 'array' failed

A few minutes may go by before it posts the message to hours between posts. Here's an example section of logs:

Any ideas what this error is telling me, or what could be causing it?

Thanks.

No idea, but try updating to the upcoming 7.7 packages from the Continuous Release repo with yum update --enablerepo=cr. With some luck it will fix your issue.
