Sonar Producer 8.5.3 allocates 2GB of memory during project saving

I have a project which is prone to crashing during saving. It has various plugins in use but none that I don't use successfully in other projects, and in equal quantities. But what is most strange about this project is that when I go to save it, the memory usage reported by Windows Task Manager jumps up from just over 800MB to up to 3GB. If the save completes, the memory is deallocated again, but if memory usage has gone up during the session, a save (or an auto-save) will usually go over the 3GB limit, crash Sonar, and I lose my edits.
 
Has anybody else encountered anything like this? And are there any settings I can use to work around this obviously bizarre behaviour? I really need to be able to finish this project and stripping out all the plugins is not an option.

There are no samplers involved in the project. And besides, it's not about there being a plugin that intrinsically uses a lot of RAM - it's about something suddenly needing 2GB more RAM purely during the save process.

Paging is enabled. Not that it makes any difference - I have 8GB of RAM and Sonar 32bit can only use 3GB of it at any time anyway, and that's the limit it hits.
 
I'm not using any V-Vocal or Audiosnap clips. I have lots of convolution in the project but the files they use are tiny (eg. <5ms) and again, they don't use much memory during normal use. This is something going wrong during Sonar's save process.
 
Global bypass on the effects bins makes no difference when the project is saved. Not surprising since all the effects are still in the project.

That is probably going to be my next step, although copying everything across is going to be a real hassle.

It crashes 100% of the time if the current memory use is high enough.

^^^ I like that idea. You may find that it comes down to a single track that's causing the problem, in which case recreating the project could be greatly simplified.

I don't know how long you want to fiddle with this particular project file, it sounds fubar. I would start to rebuild.
 
Here is an idea to see if the project has a chance for recovery. Make to make a copy of the project. Easy if you are using per-project folders, just copy the project directory to another name. Delete all tracks and see what happens. If that does not solve the problem, the project is toast.

I just got Sonar X1 Producer and for some reason I don't have guitar soft synth instrument with available patterns to create songs. Is there anyway to download them and insert them into the soft synth tab

You should start a new thread for your own question. This thread is about Kylotans memory allocation problem.
Anyway, there is no guitar soft synth with pattern library in X1 (or X2) I think (?), even though the soft synths do have guitar sounds. You need to play/compose the parts yourself, string by string, pluck by pluck. You can find MIDI files for guitar in the net for free, but pattern samples...I doubt it. They usually need something like Kontakt to be operational, and they're not free.

I ended up making a new project entirely and copying all the data over track by track. Despite having all the same plugins and data, the new project is almost half the size of the old one and seems to have no problems while saving.

Projects get corrupted sometimes; not very often fortunately.
