Description Dave Richards 2012-04-09 13:58:04 UTC
The first process run per user of LibreOffice becomes a parent process and each additional document that opens is a "child" of that process.  If the parent process deadlocks for whatever reason each attempt to open a new document simply starts a new process with no UI that appears.  The user has no indication that this has happened and can do the same step repeatedly.  On a standalone computer, a user would probably just reboot; but this will not work on a server.  

I'm not a developer, but will explain it to the best of my knowledge.  We are requesting infrastructure in Libre so that child processes "ping" the parent for a response of some type and only attempt to continue opening the file if the parent responds correctly.  If the parent fails and is deadlocked, it would make an attempt to cleanly shut down the parent (maybe grabbing a backtrace?) and then go through the normal document recovery mode.

This issue has been around for many years including with OpenOffice, but have confirmed that it happens with Libre too.

Thank you.
