APAR status
Closed as program error.
Error description
This system notice message may be seen: "Not permitting connection due to Normal throttling" and intermittent connection rejections may occur unexpectedly. The issue occurs even when system status providers show lower values than should be needed to trigger the system throttle at the configured threshold.
Local fix
Disable the system throttle as a temporary workaround, but the system resources should still be manually monitored if using this workaround. To disable throttle, from default domain using CLI: co throttle admin-state disabled exit exit
Problem summary
With throttling enabled, intermittent throttling messages might be seen in the log indicating that a connection has been rejected due to Normal throttling, even though the appliance may not be under heavy load or heavy memory utilization. This problem is more likely to be seen when using management interfaces such as retrieving operational information through SNMP. While the log message, "system notice 799 0x804000a0throttle (Throttler): Not permitting connection due to Normal throttling." is valid under spikes in memory usage, this was occurring more frequently than would be expected.
Problem conclusion
The fix is available in 3.8.2.12, 4.0.1.9, and 4.0.2.5.
Temporary fix
