| Description | This article describes a repetitive error log that can occur when advanced content processing acceleration is enabled, and how to disable it. |
| Scope | FortiGate with SOC4 hardware such as 40F, 60F, 100F and IPSA enabled. |
| Solution |
This may match a known issue ID# 1117043 under investigation and may be triggered by FortiGuard IPS updates.
FortiGate with 'cp-accel-mode advanced' may log repeated instances of 'IPSA driver update failed' in system events.

Workaround: If CPU usage was generally at acceptable levels during busy periods (for example below 60%), disable Content Processor acceleration for IPS.

To disable IPS Content Processor acceleration, make the following configuration change during a less busy time. Since this restarts ipsengine, change should be done after hours unless production traffic is already degraded.
config ips global set cp-accel-mode none end
As a side effect, this configuration change can also reduce memory usage by ipshelper during FortiGuard update. See the article: Troubleshooting Tip: Conserve mode due to ipshelper in lower end models |
