pdf conversion not happening


We are using Liferay DXP as our portal and we are using LibreOffice 5.3.3 for document conversion to pdf. The requests are made from Liferay and Liferay in turn calls LibereOffice for document conversion.

From past some days we are observing that LibreOffice is not converting the document to pdf and we dont get any errors/exceptions.

If we restart the Libereoffice then the conversion will work. We are using the following command to start the LibereOffice: sudo libreoffice5.3 "--accept=socket,host=localhost,port=8100,tcpNoDelay=1;urp;" --nodefault --nofirststartwizard --nolockcheck --nologo –norestore

We are running Liferay DXP and LibreOffice 5.3.3 on Debian 8(r4.2xlarge) in AWS cloud.

As we are using Debian, please let us know whether we have the GUI option to check/update the LibereOffice configuration.

Also please let us know, if there are any additional configuration we have to make to resolve the issue. As of now we have done the default instillation.

Would it help if we reinstall the Libreoffice?
