Issue/Introduction

Client browsers experience slowness in HTTPS access and sometimes unable to access HTTPS sites.  SWG appliance may reboot spontaneously on a random interval longer than three days.

Cause

The SSL Deep Inspection component fails to clean up session data in some situations where the client browser or remote web server terminates connection unexpectedly.  This leads to a memory leak condition within the SSL Deep Inspection component.

Resolution

To confirm and resolve a possible memory leak in the SSL Deep Inspection component, please contact Symantec Technical Support. 

Note: Tech Support please check the Internal notes for resolution.
