Excessive Logging in /var/adm/messages caused full /var and server to hang #294

Open kfr- opened 10 years ago

/var/adm/messages fills up with 50+ GB of recurring entries.

This has happened to me twice already on different servers.

I think i found a work around. Well, kind of

cp /etc/logadm.conf /opt/custom/etc/

changed /var/adm/messages -C 4 -a 'kill -HUP cat /var/run/*syslog*.pid' to /var/adm/messages -C 4 -s 2g -a 'kill -HUP cat /var/run/*syslog*.pid'

mount -F lofs /opt/custom/etc/logadm.conf /etc/logadm.conf
