# sk184065 - Root Partition Usage Gradually Increases on Security Gateway

| Property | Value |
|----------|-------|
| Solution ID | sk184065 |
| Date Created | 2025-09-29 |

| Technical Level | General |
| Products | Security Gateway |
| Versions | R82, R81.10 (EOS) |

## Symptoms

- * The root partition usage on the Security Gateway increases by approximately 1% every two days after a reboot. There is no significant increase in large files or new files in the root directory, /var, or /opt partitions.
* The output of the `lsof | grep -E "COMMAND|deleted"` command reveal thousands of deleted temporary files (objects.C.tmp) held open by the cpd daemon. Example lsof output: `COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME `  
  > `
  > cpd 1234 root ... REG ... ... ... /var/opt/CPsuite-R81.20/fw1/database/objects.C.tmp (deleted)`
* The system does not release the disk space until you reboot the Security Gateway or restart the cpd daemon.

## Cause

After each policy installation, the system triggers the cpd daemon to create temporary files (`objects.C.tmp`) in `/var/opt/CPsuite-R81.20/fw1/database/` directory. Although these files are deleted at the file system level, the cpd process continues to hold them open.  

This prevents the Gaia operating system from reclaiming the disk space, causing a gradual increase in root partition usage over time.

## Solution

This problem was fixed. The fix is included starting from:

* [**Jumbo Hotfix Accumulator for R82**](https://sc1.checkpoint.com/documents/Jumbo_HFA/R82/Default.htm)**Take 36**
* **[Jumbo Hotfix Accumulator for R81.20](https://sc1.checkpoint.com/documents/Jumbo_HFA/R81.20/Default.htm) Take 111**

<br />

If you choose not to upgrade, use this workaround:  
Restart the CPD daemon to release the disk space. Run these commands on the Security Gateway.  

1. cpwd_admin stop -name CPD -path "$CPDIR/bin/cpd_admin" -command "cpd_admin stop"
2. `cpwd_admin start -name CPD -path "$CPDIR/bin/cpd" -command "cpd"`
