Cisco Bug: CSCta62147 - Slow leak in ACS SE CSAuth memory during replication
Mar 15, 2016
- Cisco Secure Access Control Server for Windows
Known Affected Releases
Symptom: An extremely slow memory leak in the CSAuth process gradually consumes memory on the ACS Solution Engine. The memory is tied up by the CSAuth process and it gradually uses more memory after each replication cycle. Over a long period of time and several replication cycles, this eventually can use all available memory. This can be a difficult issue to spot directly as it is specific to the ACS Solution Engine and these devices don't have direct access to tools such as performance monitor. Also making diagnosis difficult is the fact that routine operation of the ACS has expected "spikes" and "valleys" in csauth memory usage that well exceed the size of this memory leak. However, in an affected device, over a long period of time and several replication cycles, the "reports and activities", "appliance status page" should show a slow trend of decreasing available physical memory. Conditions: ACS Solution Engine on affected codes replicating to another ACS Server.
