I had 100+ files open in the previous session, then closed eclipse. On a restart, eclipse just hangs with extremely high mem usuage. This problem doesn't happen with only 50 files opened.
How to prevent eclipse from loading all the previously opened files on startup? It would make more sense that the files are loaded on demand, i.e. load when focused.
I am using CDT.
opened a bug on eclipse, after the help from there, it turns out this is caused by the vrapper plugin I installed. For more details, https://bugs.eclipse.org/bugs/show_bug.cgi?id=377368
