Known Affected Releases
Symptom: Memory leak is seen under processes *MallocLite* or "IOSD ipc task" on EPAs. This can eventually causes the EPA to crash and generate a SIP_0_mcpcc-lc-ms core file. Conditions: MAC address accounting in ingress direction is configured on EPA-10X10GE or EPA-18X1GE For example: interface TenGigabitEthernet0/0/0 ip accounting mac-address input "ip accounting mac-address output" does not cause this issue. Another known trigger is when the sender HW Address count is not same as the Sender Protocol Address count. In other words, the number of source mac addresses is not same as the number of source IP addresses which cause duplicate mac assignment.
