After integrating CCS with Symantec DLP the manager service crashes due to out of memory (OOM) errors.
As a side effect, when that occurs, the user can no longer log in and a restart of the manager service is required.
You will also see accompanying hs_err files within the Vontu/protect/bin directory with the OOM
This can also occur if you have a Reporting API is pulling corrupted incidents
eTrack 2318741 has been filed for this behavior.
Workaround:
Modify the CCS requests and exclude the matches from the incident detail request from the CCS client.
Then restart the DLP Manager service and monitor the environment
