Doc Type:	Known Issue
Doc Text:	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: [Service] LimitNOFILE=16384

Description Renaud Métrich 2018-03-09 06:00:15 EST

Description of problem:

Currently, the default max open files limit for rsyslog is:
soft: 1024
hard: 4096

These numbers are too low because rsyslog connects to the system journal and this can lead to numerous file descriptors be used (see BZ 1550575 and BZ 1540132)

systemd-journald service unit has the following property:
LimitNOFILE=16384

rsyslog service unit should have the same limit set.
