CSCvj86358 | Cat3k: Excessive logging by epc_ws_liaison leading to increase in memory usage |
Catalyst C3850/C3650 switches that run a LAN Base license on Cisco IOS XE versions, as mentioned in the Products Affected section, might exhibit high memory utilization. This might also cause the switch to crash or reboot.
On Catalyst C3850/C3650 switches that run a LAN Base license, the interprocess communication (IPC) between the Embedded Packet Capture (EPC) process and the iOS process fails. These failures are logged in a file, the size of which increases over time and leads to an increase in memory usage. As a result, free memory continues to reduce with no increase in any process.
This specific issue is due to the log file written by the switch on the LAN Base license level by the EPC process of the Embedded Wireshark feature.
The affected switch might exhibit high memory utilization or memory depletion which can degrade switch performance. It might also cause the switch to crash.
The show log might display these warning messages:
May 17 21:56:23.617 GMT: %PLATFORM-4-ELEMENT_WARNING:Switch 1 R0/0: smand: 1/RP/0: Used Memory value 91% exceeds warning level 90% May 17 22:06:33.627 GMT: %PLATFORM-4-ELEMENT_WARNING:Switch 1 R0/0: smand: 1/RP/0: Used Memory value 91% exceeds warning level 90%
Upgrade to Cisco IOS XE Software Release 16.3.7, 16.6.4, 16.9.1, or later. Cisco recommends that customers review the CCO download page for current recommended starred releases in these release trains.
