Opened: Jan 30, 2015

Severity: 4-Minor

Symptoms

mcpd restarts leaving the message "The requested unknown (1936) was not found"

Impact

MCPD restarts, causing system-wide restarting of daemons.

Conditions

The conditions for this bug are somewhat unknown. Older versions of Big-IP have a simple lookup for display names. This display name table only has a select few configuration items in it, where everything else returns "unknown". So any configuration error that is generated from using a type that is not defined in the table could potentially lead to this error.

Workaround

None

Fix Information

In addition to looking up the display name for a configuration item, the lookup will now attempt to resolve the configuration item ID to a user-readable string. This solution should work for most items in the configuration, allowing for more accurate diagnostics.
