Re: URGENT: GWT build crash with out of memory
That's the only reason I use split points, to speed up load times. I split the admin pages, from the public pages, so the public don't need to d/l all the admin JS.

Re: URGENT: GWT build crash with out of memory
Split points are amazingly expensive to compute (in both CPU and memory) - I would definitely remove all split points currently under 10KB, and strongly consider removing all under 100KB, at least for an application of that size. Odds are excellent that your 4043KB file is your "leftovers" split point (you can confirm this by checking if the name of the file is the largest number in that directory) - if so, it is quite possible that removing other tiny split points will decrease the size of the leftovers and increase the size of the other larger split points. It may increase the initial download size as well, which could tell you that it could be wise to carefully put some back, but taking care to merge related split points (for example, using GWT.runAsync(Class, RunAsyncCallback) to tell the compiler that more than one RunAsyncCallback should be merged as the main file). Consider the order that your files must load in order for the application to start up - first, the 1.7MB file loads, and the app is usable until the first split point loads. Does that first split point load instantly? Does more than one load right away before the app can be used? Consider merging those split points, or entirely removing them, if they don't provide some concrete benefit (like allowing the user to start logging in while the rest of the app is still downloading, etc). Next, before the very first split point can be loaded, the "leftovers" split point is loaded - the split point with the biggest number, in your case this would be 756.cache.js (as of your last message). This must be downloaded and run before any other split point can be loaded - if this is your biggest one by a factor of of almost 10, it might not even make sense to have more than a handful of split points, unless you can find a way to bring that leftover size down, or possible merge it into the initial split point.

As already said the first thing you should do is to use -strict. This makes sure GWT compiler does not ignore compile errors. Given you have 12 compile errors, you want to fix them first.

Using -optimize 8 usually fixes the issue as the compiler will do at most 8 optimize loops then. So you might want to try that as well. I have a compiled app that is roughly half the size of yours (about 15 MB) and it compiles fine with just 8 GB Ram. But it only has about 20 split points. Using 64GB seems overkill in your case.
