## Solution

This problem was fixed. The fix is included in:

* [Check Point R77.30 Jumbo Hotfix Accumulator](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solutionid=sk106162) Take 221 and above.

Check Point recommends to always upgrade to the most recent version ([upgrade Security Gateway](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doShowproductpage&productTab=downloads&product=73) / [upgrade VSX](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doShowproductpage&productTab=downloads&product=359) / [upgrade Security Management Server](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doShowproductpage&productTab=downloads&product=184) / [upgrade Multi-Domain Security Management Server](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doShowproductpage&productTab=downloads&product=166)).

For other versions, [Contact Check Point Support](http://www.checkpoint.com/services/contact/index.html) to get a Hotfix for this issue.   
A Support Engineer will make sure the Hotfix is compatible with your environment before providing the Hotfix.   
For faster resolution and verification please collect [CPinfo](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solutionid=sk92739) files from the Security Management and Security Gateways involved in the case.

**Code was improved:** Disk space usage functions now clamp the minimum and maximum possible values to prevent overflow or underflow of the disk space counter.

**Hotfix installation instructions:**

1. Hotfix has to be installed on ***Security Gateway that acts as MTA.***

   **Note:** In cluster environment, this procedure must be performed on *all* members of the cluster.   

2. Transfer the hotfix package to the machine (into some directory, e.g., */some_path_to_fix/* ).   

3. Unpack and install the hotfix package:

   ***\[Expert@HostName\]# cd /some_path_to_fix/***   
   ***\[Expert@HostName\]# tar -zxvf fw1_wrapper_\<HOTFIX_NAME\>.tgz***   
   ***\[Expert@HostName\]# ./fw1_wrapper_\<HOTFIX_NAME\>***
   **Note:** The script will stop all of Check Point services (*cpstop* ) - read the output on the screen.   

4. Reboot the machine.
