I want to provide a quick update on this (ongoing?) issue…

I’ve made a number of changes in the last week, last night, and today that I hope will go far in working towards a full fix.

The system is much more careful about queuing up map data jobs if there’s already something running/queued. I think this will help avoid some file clobbering that may have been happening, but I have some slight concern for the situation where someone uploads multiple activities at once (or very fast) - I _think_ this could result in the LifeMap being updated for the first activity but for subsequent activities. I don’t think it’s very common for this to happen, though.

I’ve had to do some 🤓 operating system tweaks to account for the fact that there are _hundreds_ of these map data files being served. I think my recent changes will help avoid some OS-level errors that could have been happening.

I increased the size of the map data server, after noticing some out-of-memory errors hidden away in logs. This was just done last night, but I’ve already noticed a _significant_ difference in memory/swap usage.

Related to that, I noticed that my code was not closing the database files after the query was complete. 🤦‍♂️ It’s doing that now. 😬

Finally, I’ve switched the underlying package I was using to work with these database files to one that claims to be 10x faster. 🚀

This is one of the most important issues going on in CityStrides right now, and I’m _hopeful_ that my recent work will help to resolve it. 🤞 I’m really bummed that this **huge** improvement to the LifeMap has been overshadowed by all the breaking maps. Thanks for your patience, everyone!

Let’s continue this thread as-is … Please let me know if the LifeMap breaks for you again.
