Why getting libre 4.2 fatal error osl: thread:CREATE FAILED

Spreadsheet was save several hour prior. Can spreadsheet be recovered

I don’t know which machine and OS you use; I would try to shut down all and restart your PC.

If this doesn’t help please read: What information should I include in a question in addition to OS and LibreOffice version? - #4 by ROSt53

I am sure someone can help you.

this problem happened to me today, after I upgraded my version to, my OS is Ubuntu 14.04.
