/var/sentora/sessions/ directory filling up with a 15 new files per minute rate

[ericdlr]

Hi guys,

I noticed that the /var/sentora/sessions/ directory is constantly filled with new files with a 'sess_' prefix. I noticed that because today, all the files were taking up to 3 gigs at were almost maxing out the free inodes count.
I removed the 'sess_' files, but I'm still seeing new files being created. Obviously stopping the Apache server, stopped the creation of next files. I haven't seen any suspicious activity in Sentora & Apache's access logs.
I searched Google and this forum about sessions files and Sentora, but got no helpful result so far.
Any idea about what's going on here ?
Thanks in advance.

Sessions are PHP session so you can't nothing in logs! Those are users there.

Usually they are deleted after session time out.

Thanks for the enlightenment.
Unfortunately, it looks like either the sessions do not time out or PHP is unable to delete the files. I removed 3 gigs of them. The oldest was dated 2015-04-17.
For the time being, I've added a crontab to delete the sessions files on a hourly basis, but I'm still trying to understand why they are not deleted by Sentora.

For starters, Sentora is not supposed to delete them, apache/php is.
Did you change any configs?

Nope. Just a few  apt-get upgrades.


FWIW, here are some versioning infos:
Ubuntu 14.04.02
Apache 2.4.7
php 5.5.9-1ubuntu4.9

What scripts are running on your sites? It could be bad PHP coding on one of your hosted sites where sessions are not being destroyed after use. See here: http://serverfault.com/questions/624445/...verflowing

I'm also having this problem.

Same OS as OP. Sentora installation running some Wordpress sites. /var/sentora/sessions is now at 170719 files after 2 months run time.

Not sure what to do about this yet.

Just checked my sessions folder and its loaded up also. Will look into this some more as this can't be normal.
Mine has over 400,000

Solved!
Me.B You may want to review this for the installer and check if same happens on CentOS.

Ubuntu 14.04 sessions not clearing fix:
OPEN:

Code:

/etc/cron.d/php5

FIND:

Code:

09,39 *     * * *     root   [ -x /usr/lib/php5/maxlifetime ] && [ -x /usr/lib/php5/sessionclean ] && [ -d /var/lib/php5 ] && /usr/lib/php5/sessionclean /var/lib/php5 $(/usr/lib/php5/maxlifetime)

REPLACE WITH:

Code:

09,39 * * * *     root   [ -x /usr/lib/php5/maxlifetime ] && [ -x /usr/lib/php5/sessionclean ] && [ -d /var/sentora/sessions ] && /usr/lib/php5/sessionclean /var/sentora/sessions $(/usr/lib/php5/maxlifetime)

RESTART CRON SERVICE:

Code:

service cron restart

this is more a permissions issues as sessions are automaticly cleared. You can set a cron to clean files older than 1h or 1 day but better check the origin of the issue.
