Cause
Due to insufficient PHP memory limit Plesk Log manager fails to process big-sized rotated log files.
Resolution
Connect to the server via SSH.
Increase the
memory_limitvalue in/usr/local/psa/admin/conf/php.iniusing a text editor.# grep 'memory_limit' /usr/local/psa/admin/conf/php.ini
memory_limit = 512MRestart Plesk service:
# service sw-cp-server restart
As preventive measure move the old domain logs and enable log rotation by size
Connect to the server via SSH.
Move old and compressed log files from logs directory with following 3 commands:
# mkdir -p /root/oldlogs/example.com
# find /var/www/vhosts/system/example.com/ -name '*.gz' -exec mv {} /root/oldlogs/example.com/ ;
# find /var/www/vhosts/system/example.com/ -name '*.processed' -exec mv {} /root/oldlogs/example.com/ ;Set the log rotation as instructed on this article, e.g. by size of 5000kb.
