Greetings

Have any of you, had much dealings with the tcp_keepalive ?

On Solaris 8 and 9 the value is 7200000 or 2 hours. What are some of the
pit falls if this value was lowered to about 10 minutes. I have read the
RFC but was looking for people who have had real experience with tweaking
this value.

Part of the reason for tweaking, is we have a large number of PC and OS 10
users connecting to several different systems and they have been having
performance issues. Our dba decided to bring in a consultant ( that's
another story ) and they said this value should be 5 minutes. I am not
quite buying it, as I have read that there are multiple opinion on the
correct use of tcp_keepalive.
