>Description:
Samba 3.4 on FreeBSD 8-STABLE branch.
After a few days I start getting weird errors and windows PC's can't access the
samba share, have trouble accessing files, etc, and samba becomes totally
unusable.
Restarting samba doesn't fix it, only a reboot does.
log.smb:
[2010/06/10 17:22:39, 0] lib/util_sock.c:902(open_socket_in)
open_socket_in(): socket() call failed: Protocol not supported

getpeername failed. Error was Socket is not connected
read_fd_with_timeout: client 0.0.0.0 read error = Socket is not connected.
The code in lib/util_sock.c, around line 902:
/****************************************************************************
Open a socket of the specified type, port, and address for incoming data.
****************************************************************************/
int open_socket_in(int type,
uint16_t port,
int dlevel,
const struct sockaddr_storage *psock,
bool rebind)
{
struct sockaddr_storage sock;
int res;
socklen_t slen = sizeof(struct sockaddr_in);
sock = *psock;
#if defined(HAVE_IPV6)
if (sock.ss_family == AF_INET6) {
((struct sockaddr_in6 *)&sock)->sin6_port = htons(port);
slen = sizeof(struct sockaddr_in6);
}
#endif
if (sock.ss_family == AF_INET) {
((struct sockaddr_in *)&sock)->sin_port = htons(port);
}
res = socket(sock.ss_family, type, 0 );
if( res == -1 ) {
if( DEBUGLVL(0) ) {
dbgtext( "open_socket_in(): socket() call failed: " );
dbgtext( "%s\n", strerror( errno ) );
}
In other words, something in the kernel is being exhausted in my case and some
tuning is required as its failing to create sockets?

(those don't seem to fix anything, btw.)
