I haven't made any user quotas.
I checked /tmp, and there's almost nothing in there of any consequence
(an empty log file).
To look deeper, the full error was
Warning: session_start(): open(/tmp/sess_9gct9d1b866iek1p3kmo5oe0f2,
O_RDWR) failed: No space left on device (28) in
/usr/share/scuttle/www/header.inc.php on line 8
line 8 of the file in question is a "session_start();"
I looked at /etc/php5/apache2/php.ini
to see where php is storing sessions.
The relevant line,
session.save_path = "/tmp"
was commented out, so I do not know where it WAS storing them.
I uncommented the line and restarted apache, however, it seems
to have made no difference.
Now, that scuttle installation has been on this server for about two
years without ever having had such an issue.
I can't think of anything that would have changed any permissions
related to its sessions, or preventing it to write to /tmp,
but since /tmp definitely isn't full, I suppose that seems like
something to look at.
The scuttle runs as user www-data, as far as I understand,
which should have permissions to write to /tmp, no?
I'm unclear as to what java policies have to do with this,
but I know diddley about Java.
