The CPD process consumes high CPU in a VSX environment
Product
VSX (Traditional)
Version
R81.10 (EOS)
OS
Gaia
Platform
26000
Last Modified

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 starting from Take 26
- Jumbo Hotfix Accumulator for R81.10 starting from Take 110
- Jumbo Hotfix Accumulator for R81 starting from Take 89
- Jumbo Hotfix Accumulator for R80.40 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:
Enable longer refresh intervals for cpstat in VSX:
# echo "3600" > $FWDIR/conf/amon_vsx_refresh_intervalSet 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; donePerform Reboot
If you choose not to upgrade, Check Point can supply a Hotfix. Contact Check Point Support 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 files from the Security Management Server and Security Gateways involved in the case.
Hotfix installation instructions: Refer to sk168597 - How to install a Hotfix.
