Hi ! I am running redhat 9 (2.4.20-8) and I have a problem with max number of open files. I am running a database (mnesia) which manages to open approx 1024 files. I have tried different approaches to increase the limit of open files but it does not work. I have tried changing: /proc/sys/fs/file-max /etc/security/limits.conf ulimit -n Today I run my process as root (but have also tested with another user). Are 'root' treated special regarding the open-files limits ? cat /proc/sys/fs/file-max 131072 /etc/security/limits.conf * soft nofile 2048 * hard nofile 63536 ulimit -a open files (-n) 2048 ls /proc/<mnesia-pid>/fd/ | wc -l # gives approx 1024 -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
