SonicWalls running 184.108.40.206-20n and using CFS 4.0 generate Syslog files with a received value with Petabytes or even Exobytes.
When these values are input into the Reports Database, they are calculated every 10-15 minutes by the SQL database to get the total value for group level data. These numbers are so large that the calculations can not be handled by the system therefore it crashes or stops processing any new data.
Please download 220.127.116.11 from MySonicWall and apply that to your SonicWall Appliances.
If the device in question has been reporting data to the GMS/Analyzer Server while running 18.104.22.168-20n, the Reports Database will require a hotfix that is currently available on MySonicWall. The hotfix number is 176957 for GMS 8.1 and 178165 for GMS 8.0, both of these require the latest service packs and hotfixes before applying.
Note: Some users still report the same issue even after upgrading to 22.214.171.124. It has been investigated in DTS 180023 and a new hotfix has been build accordingly.
