Bug Id: | CSCuq12347 | Title: | CSR1000v/ASR1001-x - Memory leak in CPP HA due to Throughput Monitor |
|
Status: | Fixed |
|
Severity: | 2 Severe |
Description: * | Symptom:
A CSR1000v router may experience a memory leak. This will generally first manifest itself as syslog warnings:
Jan 01 02:34:56.789: %PLATFORM-4-ELEMENT_WARNING: F0: smand: RP/0: Committed Memory value 97% exceeds warning level 95%
The cpp_ha_top_level_server process is found to be consuming a slowly incrementing quantity of memory.

"CPP HA", which is a subset of the cpp_ha_top_level_server process, shows a large difference between "Allocations" and "Frees" which increases over time.

Allocations: 781851, failed: 0, frees: 396844 <-------------- Note large delta between "Allocations" and "frees"
Conditions:
Platform throughput monitor is enabled.
CSR1000v#show platform hardware throughput-monitor parameters
Throughput monitor parameters
Throughput monitor threshold: 95 percent
Throughput monitor interval: 300 seconds
Throughput monitor status: enabled <---------------
Workaround:
For the CSR 1000V:
Once memory is leaked, the device must be reloaded to recover it. In order to stop any additional memory from leaking, disable platform throughput monitor. This is not service impacting, but the device will no longer produce a syslog alert should the aggregate device throughput approach the licensed limit.
CSR1000V#set platform hardware throughput-monitor disable
CSR1000v#show platform hardware throughput-monitor parameters
Throughput monitor parameters
Throughput monitor threshold: 95 percent
Throughput monitor interval: 300 seconds
Throughput monitor status: disabled <---------------
Note that this command will not persist across a reload, so it will be necessary to re-apply the command each time the device is rebooted.
________________________________________
For the ASR1001-X:
Once memory is leaked, the device must be reloaded to recover it. No long-term workaround is available for the ASR1001-X platform. The ability to disable throughput monitoring was added to the ASR1001-X in 03.13.03.S, where this defect is already fixed.

Bug Id: | CSCut96108 | Title: | CSR1000v Fails to Read Startup-config / Boots with Default Config |
|
Status: | Fixed |
|
Severity: | 3 Moderate |
Description: | Symptom:
A CSR 1000v may boot with defaulted configurations because the startup-config fails to be properly read.
Conditions:
May be seen in Amazon AWS deployments and other scenarios. The bug is caused by a timing issue that would cause the CSR to try to read the startup-config before the device is ready. The bug fix adds a small delay in reading the startup-config to resolve this scenario.
Workaround:
Reloading the CSR 1000v several times may allow the startup-config to be read properly.

Severity: | 3 Moderate |
Description: | Symptom:
If a netflow v9 flow exporter is configured with option tables data export, after the config is saved and the router rebooted, the option table config will be missing from the running-config. The output below shows that the option tables config is intact on the startup-config, but running-config does not show the options tables config after the reload:

The above error message is only logged to the console during bootup, but not to syslog.
This only happen for netflow v9 exporter; IPFIX exporter retains the option table config after reload. Option table is not supported for netflow v5.
Conditions:
Option table config for netflow v9 exporter.
Workaround:
None.
