Sytem Error: nginx restart failed

Too many open files despite config adjustments

Seems like apache is the issue: $ sudo lsof | awk '{print $1}' | sort | uniq -c | sort -h | tail -5 2809 exim4 8138 named 15657 nginx 24092 mariadbd 65246 apache2 But raising the limit in the apache2 Service config did not help… And I am not sure whether such a number of open files is even reasonable?
