One thing to test, is to delete the db and incremental_db directories in the synthesis directory. This will cause a full recompile of all modules, and I have seen it fix issues like this in the past. It's probably caused by a corrupt db file. 

 If that doesn't work, you'll need to open a support case, and they will require your project files to reproduce it.  If you can isolate the code that causes this issue, build a small test case and submit it with your support case.  Pete

Yes, memory is getting to be more and more of an issue as the number of gates available in the device increases. Glad you have a working solution!
