Has anyone encountered a bug with their CF logs that are showing %a or %z in them in columns that should have a proper value but don't anymore? Edit: Tracing back it looks like it happened after a server ran out of disk space and after clearing space and restarting CF it has been happening ever since, clearing the cfclasses and the felix cache has not resolve the issue.

@Chad Norris Can you please share a sample here or a screenshot.

This is an excerpt from the server.log "Error","ajp-nio-127.0.0.1-8012-exec-112","03/08/25","041203","%a","null%z"

Thank you, let me check and get back to you.

@priyank_adobe I believe I was able to find the problem, somehow when the server ran out of space the log4j2.properties file got wiped out I copied the file from another good server and made the appropriate modifications to make it work with the instance and it appears to have solved the problem.

Thanks @Chad Norris, I will check with engineering as to why it is removing the properties file.
