Memory Leaks in Logging Discriminator

2015-09-25

2015-09-25

Cisco devices configured with logging discriminator may experience a memory leak or crash. When a logging discriminator is configured and applied to a device, memory leak is observed under heavy syslog or debug output. The rate of the leak is dependent on the number of logs being produced. In extreme cases, it is possible that the device might crash. To avoid memory leak, disable the logging discriminator feature.

This document lists the caveats for memory leaks for logging discriminator.

The release number in Fixed Releases column may indicate a future release.

■CSCur45606

Logging discriminator feature is broken and causes memory leak on the following platforms. Regression bug caused by the fix for bug CSCuq17177 in EEM code.

Disable logging discriminator feature until it’s fixed.
