APAR status
Closed as program error.
Error description
There is a low level network driver issue which will cause incremental memory growths on the appliance.
Local fix
The work-around is to enable IPv6 on all of the appliances Ethernet interfaces.
Problem summary
Customers using firmware releases 3.8.1, 3.8.2, 4.0.1 and 4.0.2 may observe a slow growth in memory used by the appliance. Firmware releases 5.0.0 and higher are not affected. This happens if there is IPv6 traffic in one of the networks the device is connected to and the corresponding interface has no IPv6 address configured. Additional conditions must be met for the leak to manifest, for example a packet dump running on the appliance. This is a bug in the low-level network stack, causing a small memory leak whenever a multicast IPv6 is received and IPv6 is disabled on the appliance.
Problem conclusion
The fix will be provided in 3.8.2.14, 4.0.1.12 and 4.0.2.8.
Temporary fix
Enable IPv6 on the appliance by assigning an IPv6 address to all the Ethernet interfaces in use. Setting "Enable IPv6 Autoconfiguration" control to "on" in Ethernet Interface configuration, Main tab in WebGUI is the simplest way of doing that.
