This issue has been resolved.
On Monday, February 9, 2015, Symantec released SONAR Heuristics Engine content revision 02/03/2015 r13. The update contains the 9.1.1.4 version of the SONAR engine which will prevent the crash attributed to the previous engine update released January 19, 2015 and dated January 6, 2015.
To resolve the crash, ensure your clients are running the latest SONAR Heuristics Engine content. If your computers still experience the crash after updating to the latest SONAR engine content, disable client submissions to Symantec Security Response for 14 days to allow the queued submissions to clear.
For more information on disabling client submissions to Symantec Security Response, see http://symantec.com/docs/HOWTO81000.
If you are still experiencing this problem after migrating to a SONAR engine revision of 02/03/2015 r13 or higher, create a support case and provide the following information:
A SymHelp report with Windows Preprocessor (WPP) gathered while the problem happens.
An application dump from the ccSvcHst.exe crash.
Note: If you previously disabled submissions to Security response to work around this problem, submissions can be re-enabled after SONAR updating SONAR definitions as long as it has been more than 14 days since they were first disabled.
