multiple rrdtool high (100%) cpu usage

JeffreyLewcock

Since 02:20 this morning 3 seperate systems I look after for friends have shown this problem.

Each is running at 100% CPU load and the FW is slow

After SSH'ing in I found that there are many (20+) instances of rrdtools running.

This problem looks identical to  rrdtool high cpu usage

I have tried what is suggested there which kills the rrdtool task but after a while the instances start again so I have commented out the lines in /etc/crontab.rrd for now

What is the permanent solution to this ?

Jeff

    Hi all,

    We got a response from Sophos Support.

    First of all, we had to reset the Time Zone setting (Management > System Settings > Time and Date). We were on Europe/Belfast and set it to Europe/London.

    We then rebooted both appliances.

    Once both were synced, we SSH'd on to the primary appliance and checked the Top processes to see if multiple instances of rrdtool were running. Fortunately, for the time being anyway, there weren't and CPU usage has dropped to normal levels. Will monitor it throughout the day though.

    Looks like the DST suggestion might not be so far off the mark!
