Today I had work with log files around 1-1.4Gbytes.

Opening, closing, opening a new log, closing (cycle a few) will result in the application saying there's not enough memory to open, when there's currently nothing open.

Closing the application and trying the very same log file works, immediately after restart.

It would seem there's residual data left or something to do with memory management.
