Hello Denis, Unfortunately I'm of no help here. I don't have much experience solving problems like this. I am able to reliably reproduce the crash for wkhtmltopdf https://www.google.com out.pdf indeed. It seems the upstream bugtracker contains similair cases on FreeBSD, Ubuntu and CentOS, although none contain the stacktraces.
I use wkhtmltopdf only for reports generated from our own custom HTML and CSS. These seem to work fine as long as we don't point to any https:// sources. For us that's not a problem, because we prefer having everything local anyways when generating these PDF's. When we include https:// sources we get crashes as well, although I'm not sure whether the stacktraces are the same. Does your report contain any external sources, or is it all local relative to the file? -- Frank Op zo apr 26 2020, om 14:02 schreef Denis Fondras: > Hi Frank, > > I am using wkhtmltopdf from Odoo and I noticed it crashes when > generating > reports.
