This caveat consists of two symptoms, two conditions, and two workarounds:
Symptom 1: A switch or router that is configured with a PA-A3 ATM port adapter may eventually

is removed from the switch or router and not re-inserted.

The output of the show processes memory command shows that the "ATM PA Helper" process does
not have sufficient memory. The output of the show memory allocating-process totals command
shows that the "Iterator" process holds the memory.
