Cisco FPR 2110 High Memory Utilization

[Rajavethan Veeriah]

Hi All,

We have both Active / Standby Cisco FPR-2110 Firewalls which are constantly using high memory.

Free memory: 1902561200 bytes (27%)
Used memory: 5059307600 bytes (73%)
------------- ------------------
Total memory: 6961868800 bytes (100%)

Note: Free memory is the free system memory. Additional memory may
be available from memory pools internal to the firewall process.
Use 'show memory detail' to see this information, but use it
with care since it may cause CPU hogs and packet loss under load.

Not sure what is the cause of this.   Anyone has seen this. How do I solve this.

Check if you have your NMS querying to much SNMP from your firewall, i've seen that a lot happening. Check also the Logging rules, specificaly the implicit, and if you do it on beg/end of each connection. Not sure if you doing SSL decryption but can be something to hit up your CPU/memory.
