*Rsyslog* cannot proceed if the default maximum of open files is exceeded
*Rsyslog* sometimes runs over the default limits for maximum number of open files. Consequently, *rsyslog* cannot open new files.
To work around this problem, modify the rsyslog configuration by increasing this limit to align with systemd-journald. To do so, create a drop-in file named `/etc/systemd/system/rsyslog.service.d/increase_nofile_limit.conf` with the following content:

rsyslog service unit should have the same limit set.
