After aggregate ethernet interface flap, incorrect amount of subscribers is shown in output of "show system resource-monitor subscribers-limit fpc A pic B port C".

When aggregate ethernet interface flapped and subscribers re-login, correct number of subscribers is shown in output of 'show subscribers summary port':

user@router> show subscribers summary port
Interface Count
ae2: et-2/0/5 15104
ae2: et-3/0/5 15104

However 'Current count' number in output of show system resource-monitor subscribers-limit fpc A pic B port C shows different an unexpected value:

user@router> show system resource-monitor subscribers-limit fpc 3 pic 0 port 5
Client-type : pppoe
Configured limit : 32000
Current count : 32000
Denied count : 445949

When current count number is greater or equal to configured subscriber limit, subscribers' interfaces will not be programmed on the box and system will report message similar to:

bbesmgd: LIBSDB_PORT_LEVEL_MAX_SUB_REACHED: Subscriber limit has reached max(32000) for client-type(PPPoE), fpc(3), pic(0), port(5)

At the time of writing there's no solution for this problem or acceptable workaround.
Chassis restart helps to recover from this state.
