Are there lots of connections in the connection table that are idle for long? Are those really live connections? Find the top sources and top destinations. I've seen lots of idle connections due to a broken application that would not close the TCP connections.</P></BODY></HTML> Sat, 15 Dec 2012 22:26:51 GMT https://community.cisco.com/t5/network-security/firewall-memory-utilization/m-p/2100949#M394123 Peter Koltl 2012-12-15T22:26:51Z
