The compressed logs have a huge amount of lines:
# zcat /var/www/vhosts/system/example.com/logs/error_log.1.gz | wc -l

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 = 512M -
Restart 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.
