Defect Information

CSCvc55617 Sx90 models leak Wired Memory

Problem Description

Some Cisco Web Security Appliances (WSAs) might experience a Wired Memory leak and eventually become unreachable.

Background

As a result of a Wired Memory leak, the WSA Sx90 series of security appliances might not respond and require a physical reboot.

Problem Symptom

WSAs affected by the Wired Memory leak issue experience slow responses due to a shortage of memory resources. In addition, the AsyncOS might terminate processes due to the memory shortage and this might result in network connectivity outages.

Workaround/Solution

Upgrade your Cisco Web Security Appliance to AsyncOS version 9.1.2-022 or 10.1.1-230 or later.

If your Cisco WSA is Common Criteria/FIPS certified, upgrade to AsyncOS version 10.5.0-358 or later.

Affected WSAs must be rebooted until the software upgrade is performed.

The software upgrade can be performed with the CLI or GUI of the WSA.

 

CLI

1. Enter the upgrade command.

2. Choose an option for DOWNLOADINSTALL or DOWNLOAD.

3. Choose the appropriate number associated to the upgrade version desired.

4. Complete the needed questions in order to save the current configuration.

5. Perform the reboot in order to complete the software upgrade.
