Sophos xg135 CPU always 90%

Hello,

Thank you for contacting Sophos Community!

I could see that the load-average on your device looks too high.

Have you applied DoS settings ? https://docs.sophos.com/nsg/sophos-firewall/19.5/Help/en-us/webhelp/onlinehelp/AdministratorHelp/IntrusionPrevention/HowToArticles/IPSPreventDosDdos/index.html 

Kindly share the output of below from advance shell:

#cat /log/syslog.log | grep -i  "media"

i type

 cat /log/syslog.log | grep -i  "media" 

like you tell me but not do anything  look to attached photo 

Hello,

The command is to identify if there is any errors related to disk. There are no errors and hence no output.

Could you please apply the DoS settings as suggested in KBA shared?

Also validate, the system graphs of the interface usage. Do you see any high usage of WAN or LAN interface?

Also check the disk utilization using below:

#df -kh 

i do like you do here
