The system-journald process writes to temporary storage /run/log/journal when storage mode is set to 'auto'. The persistent directory /var/log/journal that controls where the log goes (temporary or persistent memory) is usually created during BIG-IP system reboot. In some cases, /var/log/journal is not created. In the absence of this, system-journald writes to temporary storage /run/log/journal.
As it writes to temporary memory, system SWAP memory usage increases, impacting overall system performance and may result in the kernel out-of-memory killer running and killing system processes.
BIG-IP upgraded from versions prior to v14.1.0 to version 14.1.0 or later.
Perform these steps while running the upgraded 14.1.x system. 1. Create system-journald persistent log directory manually: mkdir /var/log/journal chown root:systemd-journal /var/log/journal chmod 2755 /var/log/journal chcon system_u:object_r:var_log_t:s0 /var/log/journal 2. Reboot the system.
The system-journald persistent directory is always created during reboot or when the system-journald storage option is set to 'persistent'.
