Is it normal to have 2 files over 1GB in the Caching Folder of the LiveCycle Temporary Directory?

The answer is “YES” and here is why:

Along which those two big files, there are numerous other file usually around 32mb each. Those were created by Gemfire to handle the caching and follow the predefined settings located in the cache.xml at the root of the Caching directory.

The following page gives more insight on how Gemfire works.

As far as the two >1GB files:

  • OVERFLOW_root_Local_CLASS_LOADER_CACHE_1.olg
  • OVERFLOW_root_Local_EXTERNAL_LIBRARY_CACHE_1.olg

They  are created at startup (even for new install, even though they may not hold any cache items yet) by LiveCycle to store our components which are cached and held in memory but can be pushed to overflow files to conserve heap. This technique is used to avoid creating and growing files as needed since it is a very expensive operation. Those can be seen as placeholders.
