Hey all,
SSPService.exe is bringing numerous windows 10 pro machines to a crawl in my department where the memory usage is 99-100% as seen under Processes in the task manager. This appears to be 100% of the time.
What is the current solution? These machines are all on latest updates for Sophos and windows.
Thanks,
matt
Hello,
We are also experiencing the same problem, it is really bogging down some desktops. We have also had the issue on one of our Windows servers.
The windows server in question has 16GB of RAM allocated to it (simple file server) yet the SSP Service was using around 12GB of this. Killed the service and restarted it and it is now okay. Have had to upgrade the RAM on a few machines in the last week or so due to reported slowness, I think this may be the cause.
All Sophos software is fully up to date.
That memory consumption is not right and sounds like a bug. Do you know how it grows?
If you restart SSPService and start
typeperf "\Process(sspservice)\Working Set - Private" -si 30 -o C:\ssp.csv
What does C:\ssp.csv look like after say 3 hours? Has it grown? Maybe after 6 hours? Is it a straight line or does it step up at certain times.
It would be good to get a ETL trace when it's leaking, e.g. From an admin prompt:
wpr.exe -start VirtualAllocation
leave it for up to 4 mins, ideally when leaking based on previous data. Then run:
wpr.exe -stop C:\VirtualAllocation.etl
Should be possible for Support to use this trace and the csv to say why the memory is growing, at least in the captured time frame. Problem being, it could be memory is allocated that is freed just outside the trace. The csv for a while first might make it apparent when would be a good time to trace,
Hope it helps.
Hello,
Thanks for the reply, I will try the above. The ssp service is not running currently as i have killed it off temporarily. However when you start it, the memory usage slowly goes up and up at a constant rate to around 9/10GB where it rounds off and sits.
OK, It might also be worth also creating a couple of process dumps, one after say 5 mins, then anohter after 1hr, if the mem usage has gone up enough to feel like the issue. E.g.
procdump -ma sspservice
Having downloaded procdump from Microsoft first. The 2 dmp files would be useful.

Wouldnt let me upload the .csv so I have converted it to .txt but here. I could only run for an hour and a half before users started to complain of slowness.. You can see it gradually increase to 9727123456 where it hovers for a bit before continuing to 12708950016.
Noticed this happening on another server now. Server had a total of 8GB RAM but had 20GB committed to the sspservice...eating into the storage as a "virtual memory/page file" (as i understand it anyway)

Wouldnt let me upload the .csv so I have converted it to .txt but here. I could only run for an hour and a half before users started to complain of slowness.. You can see it gradually increase to 9727123456 where it hovers for a bit before continuing to 12708950016.
Noticed this happening on another server now. Server had a total of 8GB RAM but had 20GB committed to the sspservice...eating into the storage as a "virtual memory/page file" (as i understand it anyway)
Sorry I missed the reply, given it grows so quickly I would run:
wpr.exe -start VirtualAllocation
Leave it for 3 minutes while growing, then run:
wpr.exe -stop C:\VirtualAllocation.etl
if you give that to Sophos they should be able to see the stacks responsible for the mem allocations.
