I am working with a data set that keeps causing my LibreOffice to freeze.
I am pretty sure that this is only because it is big. It is a
pipe-separated text from the US Economic Census imported into Calc, about
30 columns and around a million rows. (The actual data set is bigger, but
Calc quits at a million-odd. The complete file is about 0.8 gig.) I
suspect but can not prove that this is related to file handling somehow,
e.g. breaking down during auto-saving.


Because no LibreOffice process seemed to be using much CPU time, I assumed
that it was again frozen rather than still working (though "soffice.bin
*32" still had 1.14 gig in memory) and hit the "finish" button. 


I am running LibreOffice 4.2 on Windows 7 64-bit with SP1, on a Dell i5
machine with 24 gig of RAM. I do not recall there being a separate 64-bit
version, but the installer put it in my 64-bit programs directory.

There is only a 32 bit version of LO for Windows, so that is not an issue.
It sounds to me as though the input filter is choking on the amount of data
to be read. The RAM usage figures are smaller than I would expect for that
amount of file data, although if it is uncompressed then it is less
surprising cf. with my testing in  this
AskLO answer. I have pushed Calc v4.2 even higher on occasion. If it is a
public dataset can you post a link for others to test?
Best wishes, Owen.
