The person that contacted me was pnorman. What I was doing was creating Lake Myrtle as multiple ways under the 2000 point limit and joining them as a multipolygons, checking that it worked in JOSM and then uploading the changes. Around 3000 points split into three or four ways. Also, if I am in mad edit mode and forget to upload frequently in JOSM and exceed the 2000 node limits over multiple creation of lakes I then get the try five times error message. I shut down JOSM to avoid the same thing but have notice in Polatch the new items are added.
Also I discovered OSM Inspector but that takes for ever to update but was handy fixing a few mistakes I and others made. Noticed in JOSM even once you correct the problem it still shows up as an error. But on a whole JOSM is a better editor and my volume of work has increased as a result. As a bushwalker I am madly mapping lakes and when they say "the land of a thousand lakes" they were not kidding!

In any case there is a hard limit of 2000 nodes per way in the API (for all editors) , there is no reason that hitting is this should cause corruption though (your data might not make a lot of sense, but that is not the same as database corruption) and in general you would break any such object in to multiple ways before you reached the limit (if it is a polygon you would add the individual pieces then to the MP relation). Handling large objects is tedious in any current OSM editor however right now JOSM is the only viable choice for such edits so you are on the right track there.

Ok JOSM is frustratingly different to use than Polatch but it has many nicer things so I have bitten the bullet but are now experienced another round of problems. I was contacted by an OSM administrator and informed that I had loaded up multiple overlapping ways. I checked in Polatch and sure enough at least four overlays and to add to my increasing frustration levels when I deleted them in Polatch my computer freezes and eventually Polatch tells me it can not do this with and error message of failed update. It appears that OSM can only handle simple edits and once the number of points exceeds 2000 it fails over corrupting OSM database. In all very frustrating as I do more complex mapping task. Does make me wonder am I doing something wrong or is this typical OSM flakey behaviour?
