Bug ID: 117523
Summary: Headless doc conversion leaves soffice.bin and GPG
zombie processes
Product: LibreOffice
Version: 6.0.4.1 rc
Hardware: All
OS: Linux (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: LibreOffice
Assignee: [email protected]
Reporter: [email protected]
Description:
In the Amazon AWS Lambda environment, we are doing document conversion with
LibreOffice and Node.js. However, after we perform the conversion with
LibreOffice, there are zombie processes left behind. They are "soffice.bin",
"gpg2", and "gpgconf".
In our case, there is no init process, only Node.js (which is running as PID 1)
and it does not reap zombies. Therefore, as we continue to convert documents,
the number of zombie processes increases linearly until we hit Lambda's process
limit. The command is run synchronously and correctly waits for the main
process to finish before returning, but it looks like LO is not cleaning up as
it should.
LibreOffice should not leave behind these zombie processes.
The conversion command:
./instdir/program/soffice --headless --invisible --nodefault
--nofirststartwizard --nolockcheck --nologo --norestore --convert-to pdf
--outdir somePath someDocFile.docx

This is reproducable on the 6.0 branch circa April 30.
Steps to Reproduce:
1. Create an environment where there is no init to reap defunct processes
2. Run LibreOffice in headless mode (e.g. converting a document to PDF)
3. Observe that zombie processes remain afterward
Actual Results:
"soffice.bin", "gpg2", and "gpgconf" processes remain in defunct status
Expected Results:
No zombie processes left after conversion finished
Reproducible: Always
User Profile Reset: Yes
