protect something important with a try-except. The crash is consistant with
connection failing though. As to whether this coincides with restart messages -
I hopefully will know more when ship contacts be again.

come in as NMEA packets into a serial port.
>Does the app guard against long-running transactions?Hmm, not sure what you mean. try..finally blocks ensure transactions are
closed one way or another. The structure of the app ensures selects wouldnt
select more than 500,000 records in one transaction which don't take that

gdb to see what happens. If that worked, then I would try backup/restore but I
havent heard back.
