Run the grep command above again and inspect the config_listener.rb session limits to ensure that they are now correct.Įrror message “Stopping PCE software: DB migrations mismatch for DB: avenger_executor_dev: Missing migrations” when you try to bring the PCE to runlevel 5.Īttempted to start the upgraded PCE without migrating the database. etc/systemd/system//nfĪdd the following lines to the file and save: If the output of this command shows values for nofile and nproc that are lower than required (see Process and File Limits), provide an override file to properly configure these limits. You can verify the session limits by inspecting a running PCE with the following command: cat /proc/$(pgrep -f config_listener.rb)/limits | grep -e open -e processes

The issue can also arise if the documented installation preparation steps are not followed (see Process and File Limits) or if the values are later altered. This type of configuration relies on systemd rather than the traditional security limits for the application's session limits. It typically affects systems which have a PAM authentication configuration utilizing the loginuid module. This can cause a severe performance impact that may go unnoticed for some time. The expected session limits, configured in /etc/security/nf, might not be in effect for the PCE. This section describes issues that can arise during PCE installation or upgrade and how to resolve them.
