sophos endpoint sophos network threat protection service high memory usage

Cristiano Ravarelli

Hello Everybody,

I had 2 times this issue with SNTP on Sophos Endpoint Agent

During this, my Notebook won't respond and i have to reboot it to stop this issue. Every program was critically compromised and i had to kill every task to make the notebook able to reboot.

Anyone has a suggestion for this problem???

Thank You so much.

Cristiano

    Hi

    Could you check under SNTP.log(%ProgramData%\Sophos\Sophos Network Threat Protection\Logs\) if you find any error or anything unusual?

    Hi Cristiano,

    When I've had high memory usage from Sophos NTP in my environment it was generally caused by our backup software making many connections to the cloud to perform live backups. Every time our backup software made a network connection it would have to be scanned by Sophos NTP and eat up all the memory on the computer.  By creating a file/folder exclusion for our backup software we resolved the issue.  Support identified the issue by looking in this same log file to see many connections from a specific program.

    I don't backup the notebook.

    We work only on fileserver and I have only administrating programs on it
