Fixed In:

Opened: Dec 18, 2018
Severity: 3-Major

Symptoms

Very slow performance when loading a configuration, for example, at system start up. During this time, the tmsh process shows high CPU usage.

Impact

Slow configuration loading, or in cases with very large configurations, full config load may fail after a long wait. Slowness increases with overall configuration size and number of LTM policies defined.

Conditions

Big IP 13.1.x, 14.x. Large configuration (1 MB or larger) and at least one, but more likely tens or hundreds of LTM policies defined in the configuration.

Workaround

None.

Fix Information

Large configurations containing LTM Policies load normally.
