## Symptoms

- * The CPD process consumes high CPU in a VSX environment, when SNMP is enabled.
* SNMP queries to a large number of interfaces (more than 500).

## Cause

The 1.3.6.1.4.1.2620.1.1.25.26 OID, which is for fully utilized instance drops in CoreXL, is configured in the code to query every 2 seconds. This causes the CPD process to stall with the large amount of interfaces, leading to the issue.

## Solution

This problem was fixed. The fix is included in:

* [Jumbo Hotfix Accumulator for R81.20](https://sc1.checkpoint.com/documents/Jumbo_HFA/R81.20/Default.htm) starting from Take 26
* [Jumbo Hotfix Accumulator for R81.10](https://sc1.checkpoint.com/documents/Jumbo_HFA/R81.10/Default.htm) starting from Take 110
* [Jumbo Hotfix Accumulator for R81](https://sc1.checkpoint.com/documents/Jumbo_HFA/R81/Default.htm) starting from Take 89
* [Jumbo Hotfix Accumulator for R80.40](https://sc1.checkpoint.com/documents/Jumbo_HFA/R80.40/Default.htm) starting from Take 198

**Environments with a large number of interfaces(\>500) need additional tuning:**   
While the fix for this issue is now integrated into above mentioned Jumbo Takes, it still requires some manual modifications particularly for larger environments:  

1. Enable longer refresh intervals for *cpstat* in VSX:  
`# echo "3600" > $FWDIR/conf/amon_vsx_refresh_interval `  

2. Set the registry parameter for all VS's on the setup:  
`# for VS_ID in $(/usr/bin/netns list); do vsenv $VS_ID; $CPDIR/bin/cpprod_util CPPROD_SetValue "fw1" "refresh_fw_time_long" 1 3600 1; done`  

3. Perform Reboot
