The problem with SO_KEEPALIVE is that it usually only sends a probe every two hours, which isn't good enough. Some firewalls and such will disconnect a session long before this amount of time. And, this interval can't always be specified. See this for more info: http://www.unixguide.net/network/socketfaq/4.7.shtml "The precise value should be configurable, but I've often found this to be difficult. The only implementation I know of that allows the keepalive interval to be set per-connection is SVR4.2."
