Here's what I got: apache 1799 1 0 15:05 ? 00:00:00 httpd apache 1801 1 0 15:05 ? 00:00:00 httpd A LOT of these. and when I did ls -l /proc/1801/exe: lrwxrwxrwx 1 apache apache 0 Nov 16 15:05 /proc/1801/exe -> /usr/bin/perl It looks like some kind of script is running. Ok I ran the command: -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
