Often that's as simple as "service httpd restart", but sometimes requires some manual killing of whatever PID lsof tells you is holding them. Here's a manufactured example for training purposes ;o) [sam@samlap ~]$ sudo tail -f /var/log/messages > /tmp/list & [4] 19925 [sam@samlap ~]$ sudo lsof | grep list sudo 19925 root 1w REG 0,18 0 3287739 /tmp/list ... so we are writing to /tmp/list - lets delete it from underneath the process ... [sam@samlap ~]$ sudo rm /tmp/list ... what does lsof show now? [sam@samlap ~]$ sudo lsof | grep list sudo 19925 root 1w REG 0,18 0 3287739 /tmp/list (deleted) ... lets kill the process holding the file ... [sam@samlap ~]$ sudo kill -9 19925 [4]+ Killed sudo tail -f /var/log/messages > /tmp/list ... now lsof doesn't have a (deleted) file ... [sam@samlap ~]$ sudo lsof | grep list [sam@samlap ~]$ -- Sam -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
