Hi all,

I was just trying to upload some changes in Myanmar and got the following error message (in Potlatch & iD):

A server error occurred. Do you want to retry? (The server said: Version mismatch: Provided 3, server had: 4 of Way 380539838)

This way however was not changed by anyone else at the same time. So I don't know why this message appears. Could it be, that this way consists of too many nodes already?

I read on a mailing list that there is a problem with replication of the data from the master database to the slaves. When you upload data it goes to the master database. When you read data it comes from the slave database. When there is a replication problem, the data on the slave databases might be out of date. A newer version might be available on the master database, but you are downloading an old version from the slave.

Just be patient until the operations team has solved the problem. The problem might have been solved by the time I am writing this.

Thanks for the hint. I personally would like to see a small notification somewhere on osm.org to inform about technical issues. Then I would only edit after the problems are solved and don't waste time.

while it is not on the home page (openstreetmap.org), there is a link to https://wiki.openstreetmap.org/wiki/Platform_Status on the homepage of the wiki.

Thanks for the tip, , it would be nice to have a specific page to go to if we suspect issues to see if there are indeed issues happening. Like an outage reporting page.

@sunfishtommy I'd suggest asking in #osm-dev on IRC. That's where the most up-to-date information will be.

I am experiencing a very similar problem on JOSM. I download something from the server then make a coupe changes then try to re upload and it says I have version 2 and the object is now on version 4. I update data but it does not detect a mismatch. none of this makes sense, as I literally just downloaded from the server one or 2 minutes before. I was heavily editing one area, and it appears that the data i am uploading to the server is not matching what i am downloading from the server a immediately after.
