[Systems] sunjammer ran out of space on root partition, all e-mail delivery stopped (fixed now)

[Alex Perez]

/var/log/apache2/wiki.sugarlabs.org/wiki.sugarlabs.org-error.log had
grown to 11.7 gigabytes. I wiped it, but this wont fix the problem, only
delay when it will happen again.

All of the errors seemed to be the following:

PHP Notice:  Trying to access array offset on value of type null in
/srv/www-sugarlabs/wiki/includes/profiler/SectionProfiler.php on line 102
