Hi, currently the latest (as of today, 14 February 2021) version of Sophos Endpoint for macOS on 11.2.1 Big Sur causes issues with operating system performance.Specifically the Sophos Network Extension process, keeps ballooning in RAM until it gets around twice or more the system RAM of the system, causing other applications to crash or hang, until it cleans itself of RAM, possibly because the process runs out of memory and restarts itself.I was wondering if there's any knowledge of this or fix in the works.
I'm happy to say that we have identified the issue with the high CPU usage for the Sophos Network Extension process and will be included in our GA release.
Unfortunately there won't be an update to…
Can you confirm if you are currently using EAP for Big Sur?
I don't know how I'd verify that, but like I said, the version is 10.0.3, which, to my knowledge, fixed services for macOS Big Sur so that they're all showing protected and components installed and running.Edit: Not using EAP, and unless I'm mistaken, the EAP is over. This is all regular channel.
I also have the same problem and am using the EAP. Memory usage keeps creeping up - it's at 88GB at the moment.
We are having users report the same. I can confirm that these users are in the EAP program
Unfortunately there won't be an update to the EAP before GA which begins rollout next week at which point both EAP and GA lines will update together. If you can provide us with your updating credentials we can move you into the first rollout group, expected to release on Tue 23rd.
In the meantime, we can offer a workaround to disable the network extension. In Central amend, or create new, policies to disable:
Real-time Scanning - Internet
Once the features are disabled rebooting the machine will ensure the network extension is not loaded.
Thank you for all the feedback, it really is appreciated, and we apologize for the inconvenience
I highly suggest you do a lot more bugfixing before release. I just posted a new issue where Sophos Network Extension has a memory leak using 32GB of RAM which ends up slowing the mac to a crawl and then a KP to end things.
Noticing the exact same thing on 11.2.1 with Sophos 10.0.0.3. Sophos Network Extention leaks RAM at about 32GB and completely crashes the mac eventually.
Confirming this EAP cripples OSX 11.1 and 11.2.1
