Log rotation doesn't work for a particular domain in Plesk: error creating output file

Symptoms

• Logs are not being rotated on daily basis for a particular domain, e.g example.com.

• Running logrotate utility fails with the following error:

  # /usr/local/psa/logrotate/sbin/logrotate -v -f /usr/local/psa/etc/logrotate.conf
  copying /var/www/vhosts/system/example.com/logs/error_log to /var/www/vhosts/system/example.com/logs/error_log.1
  error: error creating output file /var/www/vhosts/system/example.com/logs/error_log.1: File exists

Cause

Temporary files were not removed due to unexpected interruption of logrotate.

Resolution

1. Connect to the server via SSH.

2. Remove the corrupted file /var/www/vhosts/system/example.com/logs/error_log.1:

   # rm /var/www/vhosts/system/example.com/logs/error_log.1

   Note: If other files are mentioned in the error, e.g /var/www/vhosts/system/example.com/logs/proxy_error_log.1, they also should be removed.
