Error "osl::Thread::Create failed" occurs when LanguageTool 2.9 is installed on LO 4.4.2 (or 4.4.1) and big document (300+ pages) is open.
Sometimes I get OutOfMemoryError (see attachment).
After that LO crashed.
This error is not occur when LT2.8 is installed,
or LT 2.9 is installed on Apache Open Office 4.1
Maybe you could use git bisect (http://git-scm.com/docs/git-bisect) on LT's code to see when the change has been introduced? Or maybe as a first step you could find out how much memory the JVM has in the LO context.
Fixed in LanguageTool daily build from 11 May 2015:
This is also fixed in LanguageTool 2.9.1, released today.

Thanks! I'll set this to NOTOURBUG as I can't think of anything better.
