The issue you are facing:
Cron appears to be failing causing several issues. I started by trying to track down some issues where I can’t upload any files because they’re all locked. Looking into that led me to this post that mentions to make sure cron is working.
The CA Bundle path changes with each invocation of cron.php.
Is this the first time you’ve seen this error? (Y/N): Yes

I don’t think the web server logs are relevant for this, but I can share them if they would me. What does seem at least a little useful is watching /tmp with inotifywait, and it produces some interesting results:
$ sudo inotifywait -m /tmp --include oc_\* -e create -e modify |
while read dir action file; do
echo "'$file' appeared in '$dir' via '$action'"
ls -l $file
head $file
done
Setting up watches.
Watches established.
'oc_tmp_asLYi3' appeared in '/tmp/' via 'CREATE'
ls: cannot access 'oc_tmp_asLYi3': No such file or directory
head: cannot open 'oc_tmp_asLYi3' for reading: No such file or directory
'oc_tmp_asLYi3-.crt' appeared in '/tmp/' via 'CREATE'
ls: cannot access 'oc_tmp_asLYi3-.crt': No such file or directory
head: cannot open 'oc_tmp_asLYi3-.crt' for reading: No such file or directory
'oc_tmp_asLYi3-.crt' appeared in '/tmp/' via 'MODIFY'
ls: cannot access 'oc_tmp_asLYi3-.crt': No such file or directory
head: cannot open 'oc_tmp_asLYi3-.crt' for reading: No such file or directory
...
# followed by many, many more MODIFY actions
...
In case it is a permissions issue, I watched again but this time used sudo ls -l and sudo head, it produced the same results.
$ sudo inotifywait -m /tmp --include oc_\* -e create -e modify |
while read dir action file; do
echo "'$file' appeared in '$dir' via '$action'"
sudo ls -l $file
sudo head $file
done
