Hello everyone, good night. Today I had a serious problem on my server. The operating system is ubuntu 10.10. The machine is HP DL120. I have 4 hard drives each with 1.5TB RAID1 +0 (software raid because this controller was not found in installation of ubuntu). I do not know why, but the machine crashed today 6:00 PM and returned after 30 minutes alone, without rebooting. The syslog messages are: Code: May 12 17:59:13 turbo CRON: (root) CMD (/usr/local/ispconfig/server/server.sh > /dev/null 2>> /var/log/ispconfig/cron.log) May 12 17:59:13 turbo CRON: (web92) CMD (/usr/bin/wget -q -O /dev/null 'http://marketing.macromind.com.br/admin/cron/cron.php' >/dev/null 2>&1) May 12 17:59:13 turbo pure-ftpd: (?@18.104.22.168) [INFO] New connection from 22.214.171.124 May 12 17:59:13 turbo pure-ftpd: (?@126.96.36.199) [INFO] New connection from 188.8.131.52 May 12 17:59:14 turbo postfix/smtpd: warning: problem talking to server private/policy: Connection timed out May 12 17:59:16 turbo postfix/smtpd: NOQUEUE: reject: RCPT from gwmail.bradescoseguros.com.br[184.108.40.206]: 451 4.3.5 Server configuration problem; from=<prvs=10654c651=[email protected][email protected][email protected][email protected] I do not understand the errors, but I suspect it is something related to the raid. What are these errors? Please, what should I do to eliminate this error? Thanks.
