On Juniper Networks Junos OS platforms with link aggregation (lag) configured, executing any operation that fetches Aggregated Ethernet (AE) interface statistics, including but not limited to SNMP GET requests, causes a slow kernel memory leak. If all the available memory is consumed, the traffic will be impacted and a reboot might be required. The following log can be seen if this issue happens. /kernel: rt_pfe_veto: Memory over consumed. Op 1 err 12, rtsm_id 0:-1, msg type 72 /kernel: rt_pfe_veto: free kmem_map memory = (20770816) curproc = kmd An administrator can use the following CLI command to monitor the status of memory consumption (ifstat bucket): user@device > show system virtual-memory no-forwarding | match ifstat Type InUse MemUse HighUse Limit Requests Limit Limit Size(s) ifstat 2588977 162708K - 19633958 <<<< user@device > show system virtual-memory no-forwarding | match ifstat Type InUse MemUse HighUse Limit Requests Limit Limit Size(s) ifstat 3021629 189749K - 22914415 <<<< This issue does not affect the following platforms: Juniper Networks MX Series.

On Juniper Networks SRX Series devices with link aggregation (lag) configured, executing any operation that fetches Aggregated Ethernet (AE) interface statistics, including but not limited to SNMP GET requests, causes a slow kernel memory leak. If all the available memory is consumed, the traffic will be impacted and a reboot might be required.
The following log can be seen if this issue happens.
/kernel: rt_pfe_veto: Memory over consumed. Op 1 err 12, rtsm_id 0:-1, msg type 72
/kernel: rt_pfe_veto: free kmem_map memory = (20770816) curproc = kmd
An administrator can use the following CLI command to monitor the status of memory consumption (ifstat bucket):
user@device > show system virtual-memory no-forwarding | match ifstat
Type InUse MemUse HighUse Limit Requests Limit Limit Size(s)
ifstat 2588977 162708K - 19633958 <<<<
user@device > show system virtual-memory no-forwarding | match ifstat
Type InUse MemUse HighUse Limit Requests Limit Limit Size(s)
