This system (hostname: $hostname) 
has entered a ‘resource conservation’ 
mode in order to prevent the rapid 
depletion of critical system resources. 
The queue is overloaded and is unable 
to maintain the current throughput.

’hostname’ - The name of 
the host.

Critical. Sent when the mail queue is 
overloaded and system resource 
conservation is enabled.

 

This system (hostname: $hostname) 
has entered a ‘resource conservation’ 
mode in order to prevent the rapid 
depletion of critical system resources. 
Queue utilization for this system has 
exceeded the resource conservation 
threshold of $queue_threshold_start%. 
The allowed receiving rate for this 
system will be gradually decreased as 
queue utilization approaches 
$queue_threshold_halt%. 

‘hostname’ - The name of 
the host.

‘queue_threshold_start’ - 
The percent threshold where 
queue tarpitting starts.

‘queue_threshold_halt’ - 
The percent threshold where 
the system will halt due to 
the queue being too full.

Critical. Sent when queue utilization 
has exceeded the system resource 
conservation threshold.

 

This system (hostname: $hostname) 
has entered a ‘resource conservation’ 
mode in order to prevent the rapid 
depletion of critical system resources. 
Listeners have been suspended 
because the current work queue size 
has exceeded the threshold of 
$suspend_threshold. Listeners will be 
resumed once the work queue size has 
dropped to $resume_threshold. These 
thresholds may be altered via use of the 
‘tarpit’ command on the system CLI.

‘hostname’ - The name of 
the host.

‘suspend_threshold’ - Work 
queue size above which 
listeners are suspended.

‘resume_threshold’ - Work 
queue size below which 
listeners are resumed.

Information. Sent when listeners are 
suspended because the work queue size 
is too big.

 

This system (hostname: $hostname) 
has entered a ‘resource conservation’ 
mode in order to prevent the rapid

‘hostname’ - The name of 
the host.

Critical. Sent when the appliance 
enters “resource conservation” mode.
