in short, my server keeps going down. i have support from an organisation listed in another forum here but they have come to the conclusion after a few scans and checking error logs that they don't seem to know what is wrong - there are no high loads or anything and they've performed a few scans and nothing is jumping out at them or i think they'd be telling me there is also no apparent set time of the day that server goes down, no every 6 hours or every 2am but it is dropping atleast once a day and sometimes 2 or 3 times i was wondering if anyone knows of anything i can be doing to monitor why it just drops or if from the information above you can see anything that i should upgrade or ... thanks

  I should also say that when the server is rebooted it stays up for a few hours or a couple of days, but it just drops again. but always without warning.

  Hi, It is best suggested to setup a monitoring script to sent you alert emails if the server load increases.
  =================================== #!/bin/bash ;We set a trigger for how high the load can get before we're ;alerted via e-mail from this script. trigger=4.00 ;We set a load variable to read the current server load from ;/proc/loadavg and only from the first column which is the live load. load=`cat /proc/loadavg | awk '{print $1}'` ;We set a response variable to the word "greater" if the current ;load is greater than our trigger that we set. response=`echo | awk -v T=$trigger -v L=$load 'BEGIN{if ( L > T){ print "greater"}}'` ;If the response is set to "greater" we run the sar -q command ;and pipe | that data to the mail command for recipient@example.com ;this sends an e-mail with the server's recent load averages there. if [[ $response = "greater" ]] then sar -q | mail -s"High load on server - [ $load ]" recipient@example.com fi ===================================
  And setup a cron job for this bash script to run periodically. */5 * * * * bash "script location" Hope this helps to identify the issue.

  Hello, The /var/log/messages and /var/log/dmesg log files are useful logs to review when attempting to determine why a system is rebooting. You may also want to consult with your data center to verify no hardware issues are resulting in the reboots. Thank you.
