Hello,
on a side note, you might be hitting the bug below:
IOS-XE router memory leak in cpp_sp_svr
CSCva63723
Description
Symptom:
1) Getting logs about committed memory exceeding warning or critical level, for example:
- on modular IOS-XE routers the ESP/0 is mentioned:
%PLATFORM-4-ELEMENT_WARNING: R0/0: smand: ESP/0: Committed Memory value 95% exceeds warning level 90%
- on the integrated IOS-XE routers RP/0 is mentioned:
%PLATFORM-3-ELEMENT_CRITICAL: SIP0: smand: RP/0: Committed Memory value 114% exceeds critical level 100%
2) We see that cpp_sp_svr uses more and more memory:
- on the modular platforms check: show platform software process list F0 sort memory
- on the fixed platforms check: show platform software process list R0 sort memory
3) In the "show platform software memory qfp-service-process qfp active" two components: Simple Classification Engine and TCAM Classification Engine get more allocations than frees and the overhead counter is increasing.
Conditions:
IOS-XE router acts as an LNS.
Radius is used to apply a policy-map to sessions.
The leak occurs when sessions are being torn down and detach operations take place.
Workaround:
unknown at this time
