Before:
/etc/logrotate.d/logs
/mnt/shared/project/var/log/*.log
{
  su www-project www-data
  rotate 30
  daily
  missingok
  compress
  notifempty
  copytruncate
  dateext
}
After:
1) create a separate additional logrotate conf file /etc/logrotate.d/logs_erp with content below (increased twice rotate 30 -> 60 and plus delaycompress):
/etc/logrotate.d/logs_erp
/mnt/shared/project/var/log/erp.log 
{
  su www-project www-data
  rotate 60
  daily
  missingok
  compress
  delaycompress
  notifempty
  copytruncate
  dateext
}2) modify current logrotate conf file /etc/logrotate.d/logs with excluding first 'erp' characters from wildcard:
/mnt/shared/project/var/log/[!e][!r][!p]*.log 
{
  su www-project www-data
  rotate 30
  daily
  missingok
  compress
  notifempty
  copytruncate
  dateext
}3) run logrotate conf file /etc/logrotate.d/logs_erp by cron additionally at 18.25
under root account
25 18 * * * logrotate -f /etc/logrotate.d/logs_erp
