Questions[debian-squeeze](server)

Currently, my PHP is on 5.3.3, how can I upgrade it? Also how can I upgrade anything? For example, if I want to upgrade phpMyAdmin as well?

I want to force logfile rotation using logrotate -f /var/log/syslog, but it's only return tones of:

error: syslog:1 unknown option 'May' -- ignoring line
error: syslog:1 unexpected text

I know that on this system rsyslogd is running. How to rotate /var/log/syslog? I want it empty.

In a new Xeon 55XX server with 4xSSD at raid 10 with Debian 6, I have experienced 2 random shut downs within two weeks after the server being built. Looking at bandwidth logs before shut down does not indicate anything unusual. The server load is usually very low (about 1) and it is collocated far away.There seem to be no power outage while the server went down.

I know that I look at /var/log but not sure which logs should I investigate and what should I look for. So Appreciate your hints.

I occasionally get locale errors and I've tried to run dpkg-reconfigure locales to fix the problem. Here's the output:

:~$ sudo dpkg-reconfigure locales
perl: warning: Setting locale failed.

I looked for /usr/bin/locale but it doesn't exist on my system. Do I need to create it? What do I put in there?

Also I found a related question that says the cause of his problem was in the sshd_config file. The file had the following entry:

AcceptEnv LANG LC_*

I'm mainly concerned that it may cause problems for my VPS, otherwise if it's nothing major I'll be happy to ignore the problem. What should I do? thanks!

I am getting a memory error in a php cron job:

Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 71 bytes) in /opt/matrix/core/lib/DAL/DAL.inc on line 830

The applicable parts of the crontab are:

$ sudo crontab -u www-data -l
MAILTO=root
# m h  dom mon dow   command
*/15 * * * * php /opt/matrix/core/cron/run.php /opt/matrix

I am running on Debian Squeeze, fully updated.

The obvious solution would be that the cli has a low memory limit (of 64MB). However, /etc/php5/cli/php.ini says it's unlimited.

$ cat /etc/php5/cli/php.ini | grep memory_limit
memory_limit = -1

I read somewhere that it could be different for different users, and since the process is running as www-data, i ran:

$ sudo -u www-data -s
$ php -i | grep memory_limit
memory_limit => -1 => -1
suhosin.memory_limit => 0 => 0

Even the apache/php.ini has a higher limit than the error is claiming:

$ sudo cat /etc/php5/apache2/php.ini | grep memory_limit
memory_limit = 128M

What am I missing? Where is this memory limit?
