Memory leak

ICSeverity

4 - Warning

Impact

High - Memory leak can lead to a full device crash, leading to an outage of the network if device is critical

Description

The memory use of a process increasing over time, and not being released, can eventually cause the operating system to run out of memory. If the system runs out of memory, it will crash. Review defect CSCsw33723 for additional information and examples of commands with large outputs which contributes to this condition. The critical threshold is 95%.

Recommendation

Avoid running commands with long outputs. It is safe to periodically restart the smand with the command: Device#test platform software process exit shell-manager RP active stateless If this doesn't provide temporary relief, you may need to reload the device. However, because the underlying condition is still present, the only permanent solution is to upgrade software to a fixed release.
