## Symptoms

- * The DLPU process intermittently stops working.

* The `/var/log/dump/usermode` directory on the DLP Security Gateway contains a core dump file for the DLPU process.

* The "`ps aux | grep dlpu`" command shows that the DLPU process consumes memory over time.

* When you run the Memory Monitor tool based on the instructions in 
  [sk163613](https://support.checkpoint.com/results/sk/sk163613), the tool shows that the DLPU process' memory consumption increases.

## Cause

There is an issue with memory allocation when the SMB Protocol is enabled in the Threat Prevention profile (in **Profiles** \> **Anti-Virus** \> **Protocol** ).

The hotfix makes the timeout of dlpu_mngr configurable in minutes based on the "dlp_config" section of $FWDIR/conf/malware_config.  

Note: This section does not exist by default  

From $FWDIR/conf/malware_config please change "dlpu_mngr_connection_timeout_minutes" to 10 Minutes   

\[dlp_config\]  
dlpu_mngr_connection_timeout_minutes=10  

Please note: For VSX environment, the configuration of the $FWDIR/conf/malware_config file is VS dependent (Reference:- <sk92224>)
