Large RADIUS messages may be dropped when processed by iRules.
The RADIUS message will be dropped, and an error will be logged that resembles: Illegal argument (line 1) (line 1) invoked from within "RADIUS::avp 61 "integer""
This occurs when a RADIUS message that exceeds 2048 bytes is processed by an iRule containing the RADIUS::avp command.
Remove RADIUS::avp commands from iRules processing large messages, or ensure that no RADIUS client or server will send large messages.
