Description (partial)

stuck ICMP connections are observed in ACE which were not getting cleared even by issuing the command "clear conn" or "clear conn all".

This problem is observed when we are running both tcp and udp based traffic flows e.g. DNS traffic as well as SSL/http traffic.In this case if because of some network failure if there is a ICMP port/device unreachable messages coming from downstream then ACE may send the ICMP connections to the upstream. These ICMP connections may be stuck forever and resulting into a resource leakage.
