Need help with CE 2.6.0.7 and Rhino R1T1

I loaded Trixbox on a brand new AMD Athlon 64 X2 dual Core 4400+ with 2G memory.
Ever since I loaded CD 2.6.0.7 this box it has been rebooting itself at random intervals. Skipping some days, and rebooting several times other days. There is never anything in either messages or full logs to indicate point of failure.
Then I installed a Rhino R1T1 a few days ago. Today it locked up and would not recover after reboot. I had to drive out to the site to restart it.

The last few entries in full log before the last lockup are:

[May 3 13:01:59] WARNING[27654] func_db.c: DB requires an argument, DB(/)
[May 3 13:01:59] WARNING[27653] func_db.c: DB requires an argument, DB(/)
[May 3 13:01:59] NOTICE[27020] app_queue.c: No one is answering queue '1' (2/0/0)

The last few entries in messages log before last lockup are:

Also, I pulled out all the WARNING messages out of the full log for today. Here's what's new since I added the R1T1:

app_macro.c: No such context 'macro-from-zaptel-1' for macro 'from-zaptel-1'

And here is an alphabetical listing of all the warning messages I'm seeing in a typical day (duplicates removed to save space).

Any help would be appreciated and would keep me from contributing even more to the wealth of the oil companies.
