We have been experiencing intermittent performance issues that causes connectivity through the firewall to run slow. This particularly impacts accessing systems over Site 2 Site VPNs and Remote Access VPN. We are running CheckPoint 15400 R77.30 in ClusterXL active / standby. The firewall has IPSec VPN, Mobile Access, IPS, Anti-Bot, Anti-Virus, URL Filtering and Application Control features enabled.
Looking at cpview, the CPU spiked on a particular core and stayed high for 6 hours before returning to normal. This time frame correlates with when the issue was reported and resolved. This issue occurred during a low usage period so doesn't seem to be caused due to high traffic / connections on the firewall.
If anyone has any ideas, thoughts to resolve this issue, please let me know.
