/etc/security/audit_warn [option [arguments]]
The audit_warn utility processes warning or error messages from the audit daemon. When a problem is encountered, the audit daemon, auditd(1M) calls audit_warn with the appropriate arguments. The option argument specifies the error type.
The system administrator can specify a list of mail recipients to be notified when an audit_warn situation arises by defining a mail alias called audit_warn in aliases(4). The users that make up the audit_warn alias are typically the audit and root users.
The following options are supported:
allhard count
Indicates that the hard limit for all filesystems has been exceeded count times. The default action for this option is to send mail to the audit_warn alias only if the count is 1, and to write a message to the machine console every time. It is recommended that mail not be sent every time as this could result in a the saturation of the file system that contains the mail spool directory.
allsoft
Indicates that the soft limit for all filesystems has been exceeded. The default action for this option is to send mail to the audit_warn alias and to write a message to the machine console.
auditoff
Indicates that someone other than the audit daemon changed the system audit state to something other than AUC_AUDITING. The audit daemon will have exited in this case. The default action for this option is to send mail to the audit_warn alias and to write a message to the machine console.
ebusy
Indicates that the audit daemon is already running. The default action for this option is to send mail to the audit_warn alias and to write a message to the machine console.
getacdir count
Indicates that there is a problem getting the directory list or plugin list from audit_control(4). The audit daemon will hang in a sleep loop until the file is fixed. The default action for this option is to send mail to the audit_warn alias only if count is 1, and to write a message to the machine console every time. It is recommended that mail not be sent every time as this could result in a the saturation of the file system that contains the mail spool directory.
hard filename
Indicates that the hard limit for the file has been exceeded. The default action for this option is to send mail to the audit_warn alias and to write a message to the machine console.
nostart
Indicates that auditing could not be started. The default action for this option is to send mail to the audit_warn alias and to write a message to the machine console. Some administrators may prefer to modify audit_warn to reboot the system when this error occurs.
plugin name error count text
Indicates that an error occurred during execution of the auditd plugin name. The default action for this option is to send mail to the audit_warn alias only if count is 1, and to write a message to the machine console every time. (Separate counts are kept for each error type.) It is recommended that mail not be sent every time as this could result in the saturation of the file system that contains the mail spool directory. The text field provides the detailed error message passed from the plugin. The error field is one of the following strings:
load_error
Unable to load the plugin name.
sys_error
The plugin name is not executing due to a system error such as a lack of resources.
config_error
No plugins loaded (including the binary file plugin, audit_binfile(5)) due to configuration errors in audit_control(4). The name string is -- to indicate that no plugin name applies.
retry
The plugin name reports it has encountered a temporary failure. For example, the audit_binfree.so plugin uses retry to indicate that all directories are full.
no_memory
The plugin name reports a failure due to lack of memory.
invalid
The plugin name reports it received an invalid input.
failure
The plugin name has reported an error as described in text.
postsigterm
Indicates that an error occurred during the orderly shutdown of the audit daemon. The default action for this option is to send mail to the audit_warn alias and to write a message to the machine console.
soft filename
Indicates that the soft limit for filename has been exceeded. The default action for this option is to send mail to the audit_warn alias and to write a message to the machine console.
tmpfile
Indicates that the temporary audit file already exists indicating a fatal error. The default action for this option is to send mail to the audit_warn alias and to write a message to the machine console.

See the section on Solaris Auditing in System Administration Guide: Security Services.
This functionality is available only if the Solaris Auditing feature has been enabled. See bsmconv(1M) for more information.
If the audit policy perzone is set, the /etc/security/audit_warn script for the local zone is used for notifications from the local zone's instance of auditd. If the perzone policy is not set, all auditd errors are generated by the global zone's copy of /etc/security/audit_warn.
