The message you would see is "OpenRG is going for reboot by IPC command" or something similar.
Nope I haven't seen any of those at all, what I always get when it reaches about 2 weeks is lines like the following (from bottom upwards):
05:17:09, 23 Jan. (1068783.850000) CHAP Receive Challenge

23:41:33, 22 Jan. (1048647.070000) Admin login successful by 192.168.2.72 on HTTP
The Admin login was me due to slow speed where I just checked the logs.
Actually that's a lie, I just saw some of those IPC lines in the System Logs:
02:26:35, 07 Jan. ( 40.460000) The system is UP!
02:25:32, 07 Jan. (1262312.660000) The system is going DOWN for reboot.
02:25:32, 07 Jan. (1262312.660000) OpenRG is going for reboot by IPC command
02:25:27, 07 Jan. (1262307.660000) OpenRG will go down for reboot in 5 seconds
11:47:22, 23 Dec. ( 38.390000) The system is UP!
11:46:22, 23 Dec. (1211146.960000) The system is going DOWN for reboot.
11:46:22, 23 Dec. (1211146.960000) OpenRG is going for reboot by IPC command
11:46:17, 23 Dec. (1211141.960000) OpenRG will go down for reboot in 5 seconds
And that was the latest one that we have in the logs, and if you do the maths you will see 14 days between remote reboots.
And like I have said we don't loose sync to the exchange, but we do loose connection to the BT Network.
It is strange that we have never had a stable connection to BT's Network for longer than 2 weeks where as with our last ISP (Zen) we hardly had any reconnects and would be connected up for several months, but the current issues are probably down to all the bad weather we are having lately.
The only time we have lost connection and the HH4 reboots was when I asked for our SNR to be reset back to 6.0 dB due to the rain causes our SNR to rise and rise until it just fails to sync. BT are aware of this and are happy to reset our SNR and is probably why our PCP cabinet is currently being re-installed.
