OpenCPN Stops Running

[BobLarkin]

I have been running OpenCPN under Ubuntu 10.04. This summer, the program consistently stopped running after 30 minutes or so. I was near Seattle at the time, and this problem has not occurred at any other area!

I hunted the forum for a similar report and could not find one. Someone please redirect me if this is old news.

Here is the deal. The setup:
LaptopIBM Thinkpad R40e.
Ubuntu 10.04
OpenCPN 2.3.1
Garmin 48 GPS and SR-161 AIS NMEA through an Edgeport4 adapter

OpenCPN would start, apparently correctly, run for 30 minutes or so and then close, leaving no open window. The log appears to my untrained eyes to be normal for opening, but showing no hint of closing. The last log entries were:
09:33:57 AM: Loading chart db version: V016
09:33:57 AM: Chartdb: Chart directory list follows

09:38:00 AM: Initializing Chart /home/bob/Documents/Charts/ChartActive/Puget Sound/18452_1.KAP

Each subsequent rRe-opening of OpenCPN would produce an open window for a second or so, then close with the log ending:
10:07:11 AM: GPS Watchdog Timeout is: 6 sec.
10:07:11 AM: Initializing Chart /home/bob/Documents/Charts/ChartActive/Puget Sound/18449_1.KAP
(in one case there was also a LOGBOOK entry)

If I shut down Ubuntu, and did a cold start, OpenCPN would run again for 30 minutes, give or take.

Unfortunately, I had a boat to take care of, and was not in a position to play much with software. I really wanted the AIS data, and so ran Fugawi under Windows, the stuff I was trying to get away from! This all ran fine for the rest of the trip.

The OpenCPN log for that period is posted at:
http://www.proaxis.com/~boblark/opencpn_7July2011.log
This includes:
04:09:59 PM: 2011-07-07 Previous day, clean open and clean close (manual).
09:33:55 AM: 2011-07-07 Ran for perhaps 30 minutes and closed
10:07:09 AM: 2011-07-07 Restart, closed in a second or so
10:07:36 AM: 2011-07-07 Restart, closed in a second or so
10:08:05 AM: 2011-07-07 Restart, closed in a second or so---Note this included a LOGBOOK: entry
01:30:23 PM: 2011-07-07 Later in day; a restart of Ubuntu and OpenCPN. This ran for 20 min or so and then self closed.

The only thing that was obviously different from previous or later uses of OpenCPN, all of which were flawless, was the amount of AIS traffic. In operation that failed, I was 15 miles west of Seattle, and there was much AIS traffic. Normally I am in waters that have limited numbers of big boats, and have not had any hint of this problem.

Any ideas where I might look for a solution?? I will have future opportunities to run all this in the Seattle area in months to come. So, any ideas of experiment design would be good.

Thanks, Bob

I sure will try that, hopefully on an A/B basis to make sure the old problem is still around. Thanks, Bob
