We have received your zip file. Thanks for sending it. I have seen several errors in the php log:
[20-Nov-2019 01:58:28] WARNING: [pool wordpress] server reached pm.max_children setting (5), consider raising it
Can you try increasing the value of the pm.max_children parameter in the /opt/bitnami/php/etc/bitnami/common.conf file and restart the services?
sudo /opt/bitnami/ctlscript.sh restart
Please note this value depends on your server size and that increasing it too much for a small server may cause performance issues.
Can you also run the following command to check the free space on your server? I see something weird in the support bundle and want to make sure is not a space issue.
