> SUNRPC: Use shutdown() instead of close() when disconnecting a TCP
Hi, it seems I have the same problem, with slightly different config. Client is
2.6.24.7 (OK), 2.6.25-rc1 and later (25,26,27,28-rc6) (fail). On client I get
FIN_WAIT2 state. The server is FreeBSD 7.0-STABLE (have two of them with the
same behavior). Fastest way to get into trouble is to use automounter so it
cycles the ports - when it gets to one in FIN_WAIT2 the machine gets "dead".
Reversing the patch with 2.6.27.4 seems to help, before the machine gets stuck
in ~ hour, now it is up for 16hours and seems ok.

Once or twice I prove with tcpdump that client send FIN, got ACK from server but
no FIN from server.
