Currently have Sophos Central with Sophos Endpoint running on several machines here, i was the first to update to the latest Windows 10 1903 Update and noticed after the machine sitting idle for a while that the above service is consuming a lot of RAM.
Any solutions to this?
I will need to contact my team regarding this to check if we have seen many reports similar to this issue.

I've heard back from my team and can confirm that we haven't noticed many reports regarding this issue. I would request you all to raise a support investigation with Sophos technical support team.
Well you've noticed reports from us!
Anyway there are already support cases open and according to mine there are at least a dozen reports of this problem and the issue has been been passed to Global Escalations and Development who are working with Microsoft.
Anything else you need us to keep you up to date with just let us know.
We are having the same issue.
Is it only on 1903 computers?
Have you tried:1. Disable Tamper Protection on the EP if enabled and reboot does it continue?2. Disable EDR if enabled? Evidence of it being enabled | disabled is:HKLME\SOFTWARE\Sophos\EndpointDefense\PolicyConfiguration DWORD edr_enabled 1|0Note: In Central this policy setting is in the ThreatProtection policy and called:"Allow computers to send data on suspicious files, network events, and admin tool activity to Sophos Central".3. If you rename sohosed.sys under: \windows\system32\drivers\ (will need to disable Tamper protection) and reboot.Does it happen then?
Disabling tamper protection does not resolve the problem.
EDR is not enabled.
I'd need to know more about the consequences of preventing the Sophos ED driver from loading before doing that but if it prevents SSPService from starting it will definitely resolve the problem!
Useful to know, thanks for the update. Maybe lets not worry about SED driver immediatly.
What about in the "Threat protection" policy if you disable:"Enable Threat Case creation"?After doing so in Central, on the client: "snapshot_upload_uri" under:"HKEY_LOCAL_MACHINE\SOFTWARE\Sophos\EndpointDefense\PolicyConfiguration"...will go from having a URL to being an empty string on the client once disabled.This is something else that SSPService is involved with.Also, any errors of interest in here:"C:\ProgramData\Sophos\Endpoint Defense\Logs\sdr.log"Regards,Jak
SED driver has some unfreed allocations. This seems generally stable however,
SDR log has one per minute of the following:
SDR Proc Error Failure encoding all processes! Func: 2 Type: 3 BufLeft: 93772
Do you see the problem if you disable "Enable Threat Case creation"?Also, if you "restart" the computer, how quickly does the problem occur? Does it take minutes or hours?Does it happen at a certain time(s) following the startup and is that the same time(s)? if it starts occurring at a certain time each day, what happens on the machine at this time which could be the trigger?I suppose the question is, can you predict when it will occur?Regards,

Have only just disabled this so ... dunno. Will let you know.

Well it generally takes hours for the problem to reach the point where a machine actually crashes.
But that's not to say it doesn't *start* happening soon after boot, it's not easy to tell increasing memory use due to increasing system activity from increasing memory use due to a leak.
(For users experiencing the problem crashes per user per day range from 0.5 to 2)

I promise that if I do find out I will not hold this information back.
Thank you for your response. To get better data on when it might start, I would suggest:
1. Restart the computer.
2. Once logged in, start an admin prompt and run the command:typeperf "\Process(SSPService)\Handle Count" "\Process(SSPService)\Pool Nonpaged Bytes" "\Process(SSPService)\Pool Paged Bytes" "\Process(SSPService)\Private Bytes" "\Process(SSPService)\Working Set" "\Process(SSPService)\Working Set - Private" -O %temp%\sspservice.csv -si 30
Note: It's all one line.
This will sample some of the Windows performance counters for the SSPService every 30 seconds and record the data in %temp%\sspservice.csv.If you leave it running until the issue starts and then leave it as long as possible when the issue is occuring it will tell us:1. When it started relevant to startup.
2. The rate of the memory usage over time.Maybe you can attach the file here when complete? Ideally repeating the test twice following the restart to see if:
1. It does start at a certian time.2. It starts at a certain amount of time following startup.I suspect it's pretty flat, some event takes place and then it goes up.Many thanks again,Jak
