Comment 9 for bug 1920190

@Manu
Can you please attach the error_log too. It is located in the var/log/cups directory.
Please make sure to enable the log level to debug or debug2 before uploading. You can get an idea about how to do it in the following link:- https://www.thegeekdiary.com/how-to-enable-cups-debugging-on-centos-rhel/

Also if possible then try to separate the error logs of different print jobs. For example you can send the print job first for test12.pdf and then copy from the error_log and then you can erase that log and can send a print job again for test48.pdf(which causes significant RAM usage.) and then copy the new error log.
