The output of the show processes memory command, collected in regular intervals, shows a
memory leak in the ISDN L2 process. The amount of memory that is held by the ISDN L2 process
is very large, and the amount of free processor memory is small when the router reloads
unexpectedly. This symptom is not observed on a Cisco AS5850, but may also occur on this platform
when it runs under stress for more than 24 hours.
