The question is: why does auditd even log to the journal?

journald detected that it got flooded with too many messages in too
short a time from auditd. if this happens then something is almost
certainly off with auditd, as auditd is not supposed to flood journald
with messages, after all it maintains its own auditing log database.
Please ping the auditd folks for help
Lennart

journalctl --disk-usage
Archived and active journals take up 1.1G on disk.
Initially we saw:
16733 PATH
5070 SYSCALL
5024 CWD
3765 AVC
323 CRYPTO_KEY_USER
223 USER_START
222 USER_ACCT
222 CRED_ACQ
220 LOGIN
220 CRED_REFR
218 USER_END
218 CRED_DISP
46 USER_LOGIN
12 EXECVE
4 USER_AUTH
2 CRYPTO_SESSION
1 USER_ROLE_CHANGE
1 USER_CMD
1 SERVICE_STOP
1 SERVICE_START
1 BPRM_FCAPS
so we blocked type PATH in audit.rules
But we are still seeing 100K of dropped/suppressed messages.
Note: systemloglevel = INFO
Centos 7 1708 3.10.0-693.2.2.el7.x86_64
systemd.x86_64 219-42.el7_4.1
Now we are required to have full audit rules and does this look like at
rate limiting issue or an issue of journal not able to handle the
traffic to logging?
Error we are seeing from services that have silently failed, in this
case glassfish..
systemctl status -l glassfish
● glassfish.service - SYSV: GlassFish start and stop daemon
Loaded: loaded (/etc/rc.d/init.d/glassfish; bad; vendor preset: disabled)

Process: 1328 ExecStart=/etc/rc.d/init.d/glassfish start (code=exited,
status=0/SUCCESS)
Warning: Journal has been rotated since unit was started. Log output is
incomplete or unavailable.
Eventually glassfish will fail but it wont kill the service so we never
get an nms service down trap from the OID.
Please let me know if further info is needed or if certain limits need
to be adjusted.
Thanks,
Brad Zynda
