<pre>Description:
When using LibreOffice in server mode, asking him, via UNO (Python 3), to
convert a ODT file into PDF, with some ODT documents, LibreOffice never
produces the resulting PDF file, never returns any error message but continues
to run forever, consuming 100% of available CPU.
Steps to Reproduce:
This is clearly HARD to reproduce:
- it requires an application server to run (Plone or Appy);
- LO running in server mode;
- ask, from the UI, to render a document in PDF format;
- the Appy framework is used behing the scenes, produces an ODT file from a
document template, itself being an ODT file (see
<a href="http://appyframework.org/pod.html">http://appyframework.org/pod.html</a>), and asks LibreOffice to convert it to PDF.
Moreover, if I try to reproduce it on a DEV environment, it works. It happens
only on a production server, on heavy load.
Actual Results:
LO runs forevere, and takes 100% CPU
Expected Results:
LO produces the requested PDF file or a clear error message via the UNO bridge.
Reproducible: Sometimes
User Profile Reset: No
Additional Info:
We are a community of developers and companies using the Appy framework and
LibreOffice in server mode to produce millions of documents per year, on
hundreds of Appy-powered application servers.
This bug is really blocking for us and occurs at least since LibreOffice 6.0
through LibreOffice 7.0.1.2 (last tested version).
We would be very grateful if you have any idea of what happens here. We have no
control on the LO server component, it is for us a black box, without any log
or error message, running at 100% CPU.
Thanks a lot, LO is a killer app!
Server config is:
Ubuntu 18.04 LTS
