Aside from some call recordings backups that had to be moved out of /var/spool/asterisk/backup/[my own rec backup folder] because lstat was failing on them, whoopsing heavily, then I had to run fwconsole chown, and silence the firewall 
and I’m all green 
Thanks !
Would be nice to know what the issue was.
[EDIT: more accurate description]
The upgrade process finished like normal, and told me to reboot. I did.
[it did have a few whoopses but otherwise seemed to tell, it finished as normal]
Then I logged on to GUI and it was all Could not connect to Asterisk.
So I went to cli via ssh, and ran fwconsole chown and/or fwconsole restart , which whoopsed on cdr backup files [list below].
(where exactly this happens in the upgrade process, I can’t check right now - but if you are saving some upgrade log, somewhere, I could send it over for analysis)
So I moved them out of their designated place in /var/spool/asterisk/backup/[backup name] and then, fwconsole chown and fwconsole restart has succeeded, and the GUI worked again then.
[as I now went to console and did ls -l on these backup files]
I think, the problem really was
[root@pbx ~]# ls -l
total 23100468

the size of these files (my distro is 32 bit).
I have had the same issue with call recordings. Restoring a backup and the file sizes were to big. Moved them to another directory and did a fwconsole clown and tadaaaa all green
is the Framework 13.0.153 update related here?
Not sure what you are asking specifically.
specifically about the line of changelog in framework .153, saying
13.0.153: Fix for filesize function
in relation to fwconsole chown whoopsing on the large files (backups specifically)
I dont think it’s related to this at all. Everything is related to a bug report.
OK thanks
(there was no ticket number linked in framework changelog, hence I asked)
