I'm seenig quite a few listening tcp sockets, too.
A few by gnome-session. On SX:CE build 104.

IceListenForConnections() seems to open these
listening tcp ports. Stack backtrace for gnome-session
looks like this:

Gnome-session (gsm-xsmp-server.c) seems to include this
piece of source code, and as far as I can tell, there is no Xtrans.h
header delivered with Solaris (SX:CE 104), and libICE doesn't
define a public _IceTransNoListen entry point:
00465 #ifdef HAVE_X11_XTRANS_XTRANS_H
00466 /* By default, IceListenForConnections will open one socket for
each
00467 * transport type known to X. We don't want connections from
remote
00468 * hosts, so for security reasons it would be best if ICE didn't
00469 * even open any non-local sockets. So we use an internal ICElib
00470 * method to disable them here. Unfortunately, there is no way to
00471 * ask X what transport types it knows about, so we're forced to
00472 * guess.
00473 */
00474 _IceTransNoListen ("tcp");
00475 #endif
For that reason we seem to get the default behaviour mentioned in
the above comment, "IceListenForConnections will open one socket
for each transport type known to X" ...
