Symptoms: The following error messages may appear on a router when bringing 
 up PPPoX sessions, and the router will not be able to establish new sessions:
 %AAA-3-ACCT_LOW_MEM_UID_FAIL: AAA unable to create UID for incoming calls 
due 
 to insufficient processor memory
 %AAA-3-LOW_MEM:  Author process is unable to handle the incoming packet due 
 to low memory
    
 Condition: This is seen when  a large number of PPPoE sessions (approximately 32000) are attempted, with edge  configuration + traffic classes using radius-based authentication. 
Only up to  29000 sessions may come up before hitting the above error.
