2013-11-10 16:30:16 - BBQ Blocks Rounding by Server
During the Lake Superior Lights race erinbrook33 reported that after rounding Michipicoten Island the Server would not recognize his subsequent rounding of East Michipicoten Light & dropped the ability of his boat from further scoring.

It was observed by Laozi that his boat BBQ'd along that costal region where the rounding was to be recorded.

This should be reviewed in case there is, for whatever reason, the possibility for the server to lose track of a boat's continuity during the progress of a race.

Having checked the track for this boat the BBQ was indeed at the 240° bearing to the mark that is listed in the NOR for this mark's rounding requirement.

bbq happened at the exact point the server should register the rounding. I don't think that's coincidence.

I know the DevtDudes will look at this but I've emailed them too... what a fascinating issue... not for erinbrook though. In all my time on Sailonline I've not encountered this.. I am wondering if it is the nature of the bbq and the way in which the server "bounces" a boat back offshore.. if it did so to the rounded side of the mark, then it would have scored as a bbq and not a rounding... with the subsequent jump continuing to compound the problem.

Hopefully erinbrook will have a valid email address and once this is sorted out we can email them with what we discovered.

The server logs unfortunately don't reveal what exactly happened, but this is my hypothesis.

Even if the bbq happened really near, it actually was just after the rounding. You can see here that at 2013-09-17:00 the next mark was already Caribou Island Light but at 19:00 it was switched back to East Michipoten Light while the boat didn't move.

http://sol.hmm.iki.fi/sollog/boat/633/erinbrook33/

At 18:23 the sailing engine process crashed while saving cached values to DB. The watchdog restarted the engine instantly but apparently erinbrook33's rounding information was not saved to DB and thus the boat was marked as not rounded even if the locaton stayed the same.

As long as I have been the admin, the sailing engine process has had the habit of occassionally dying. It happened with the old server and has continued with the new one. The problem in fixing that is that the sailing engine has to be constantly running.

So far I have considered that the sailing engine is "good enough" and just kept an eye on it. I think there has once before been a similar rounding issue during the 1.5 years I have had access to the server (at least only one other has been brought to my attention).

However, as I have now learned how to install the full SOL system to new servers, we now also have a test server which I can see if we can fix the sailing engine to be more robust. The problem is that even with normal use the problem happens 1-2 times a week, so finding the issue is not necessarily easy and takes some time.

Thanks to email discussions with brainaid yesterday, we now know the probable reason why the sailing engine occassionally dies. Fixing that needs some thought though but we are working on it.

New Ice Age 2026 - Browerville to Longyearbyen


Our 2026 long-distance ice-boating challenge continues with a second race in Arctic waters, now from Browerville, where we arrived less than a month ago, continuing east, back to Svalbard’s Longyearbyen, leaving Canada’s Ellesmere Island to port and Denmark’s Greenland to starboard. It’s about 2500nm, which, if there’s wind at all, should, well-wrapped in your DN-cockpits, not take you more than a day or three, thus to complete your first (of several) online circumnavigation of the planet of 2026!

Cross the Convergence 2026 - Samoa to Hawaii


The second race of our new series of ocean voyages across the World’s convergence zones, takes us northward again up the Pacific Ocean, now from Samoa at 13.5 degrees South, across the Equator to Hawaii, famed for its breaking surf and active volcanoes, on the edge of the Tropic of Cancer at 19.5 degrees North. It’s 2300nm, so we’ll take our very steady Steinlager II. Race #1982

Beketov by Balloon 2026 - In Siberia


Way-back-when France and England, and Spain as well, were squabbling about who should control what of North America, only to lose the most of it to their own insurging colonists, their eastern European neighbour empire, Russia, was quietly assimilating vast, thinly nomadically populated territory of its own – Siberia! Amongst the many explorers and adventurers that served Russia so well in these conquests was the Cossack hetman Pyotr Beketov. Let’s pretend we’re he and eschewing horseback, let’s travel by balloon from Yekaterinberg to Krasnoyarsk – just a short 2000km (1100nm) section of the Trans-Siberian Express’ 9289km!

West Papua to Oregon 2026

Our next race in our Ocean Championships is the first of a series of great natural migrations we will track in 2026. The leatherback turtle is the most widely distributed marine reptile on planet Earth, and chooses to breed in warm tropical waters, but prefers to forage in more temperate habitats, travelling thousands and thousands of miles effortlessly annually to maintain this way of life. Our race will follow one of the typical trips of this turtle, from breeding grounds in the seas off West Papua to the coast of Oregon. It’s only 5900nm, so to keep up, but in comfort, we’ll follow in our Gunboat 90.
