Odd sleep behaviour on MacPro

But every now and then (I think it is after a reboot), going to sleep results in the ethernet going off which causes all the remote X windows to timeout and be lost.

I have X windows running on the Mac. Windows come from other systems, displayed on the mac (as well as some local xterms).

Usually, when the Mac goes to sleep, the displays go off, but the ethernet remains on and enough of the Mac remains awake to maintain the remote x window connections.

Energy saver is currently set to:

Computer sleeps: 1 hour Display Sleep: 12 minutes

Put the hard disk to sleep: yes Wake for Ethernet network access: no Allow power button to put computer to sleep: yes Start up automatically adter a power failure: YES

Note the later: after a power failure where the mac was asleep, it does not power back on automatically.

I haven't changed those settings in ages.

I suspect some application, possibly Transmission (for torrents), does something to the mac to prevent it from ever going to sleep completely and this survives after Transmission has quit but is not reflected in the System sesstings.

is this possible ?

Is my only option to set the "Computer Sleep" to "Never" ? is there a "half asleep" setting where background stuff continues, but GUI stuff is suspended ?

I'm not sure if it can survive past Transmission being quit, but there is an option to turn off Transmission interfering with your settings entirely in its Preferences (Network tab).

"Prevent computer from sleeping with active transfers"

The wording would tend to indicate that even with transmission running, it would still go to sleep if there were no active transfers. Perhaps the setting is so strong that it survives not only the lack of active transfers, but the quitting of the application :-)
