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 ?

    Same issue here, and also started around the same time.


    Firmware version: 9.714-4
    Pattern version: 222574

    Running Sophos UTM [home] on a VM for almost 10 years. Tried a reboot but the rrd process was consuming 98% of the CPU again within a few minutes.

    I rebooted the passive hardware appliance a while ago. Took an age syncing with the primary unit. CPU on the passive is creeping up gradually. Fully expect it to hit 100% within the hour.

    2 x SG450 (Version 9.714-4)

    HA = Active-Passive

    Mine since rebooting is holding at 15% CPU, but friends went right back to 100% after reboot...have run the kill commands...now dropped to single digits...lets see how long it lasts...

    killall /usr/local/bin/create_rrd_graphs.plx
    killall rrdtool

    I think when the cron job kicks in it'll be back !

    I think the cron job times are unique to the UTM they're on as the jobs on the 3 I look after are all different

    So, 12 hours later, my CPU usage is still in single digits. 

    I did the following:

    Kill the tops using the two commands above

    Rebooted the UTM

    Generated an Executive report

    Once it had generated, I rebooted the UTM again.

    It's been stable since...I might have just gotten lucky, so I asked friend to do the same on his UTM, same outcome, now stable around 15% usage for him and 5% for myself.

    I did not comment out any jobs etc.
