Hibernation High RAM Usage [NBZ]

The bug/issue
1. What you did:
Installed latest v5 CIS, Hibernate computer, resume, then log back on.
2. What actually happened or you actually saw:
sluggish performance immediatley afte logging on. Checked task manager, cmdagent.exe was utilising 15-25% cpu usage and about 100mb of ram.
3. What you expected to happen or see:
Normal behaviour (IE cmdagent not consuming massive amounts of resources) Because there is probably a backlog of updates, CIS should apply the updates one by one over an hour or so perhaps with a balloon popup telling the user the update progress as a pecentage, or delay applying updates 15 minutes after log on WITH a pop up balloon stating that ‘cis needs to clear the backlog and will begin updating in 15 minutes etc’ and the option given to the user to install now by clicking the balloon message or something.
4. How you tried to fix it & what happened:
Tried installing latest .1142 update.
5. If its an application compatibility problem have you tried the application fixes?:
Don’t think its an application compatability issue.
6. Details (exact version) of any application involved with download link:
7. Whether you can make the problem happen again, and if so exact steps to make it happen:
I usually hibernate my pc in the evening rather than switch it off. The following morning, the issue occurs after resuming from hibernation and logging on to your user area.
8. Any other information (eg your guess regarding the cause, with reasons):
Because i hibernate my pc for long periods of time, i beleive the issue is caused because CIS is installing all the virus database updates from the previous 12 hours or so. This kind of renders hibernation feature useless as its quicker to do a fresh boot in these circumstances. AFAIK, there has never been an issue with CIS causing hibernation to fail completely.

We’d really appreciate it if you could just add in the requested info to 1, 4 and 5. We need people to double check as people frequently change things and forget! By default profile do you mean Proactive or Internet Security (both are possible)?

To further this we’d also need to understand how you think CIS should behave in more detail. Maybe delay applying the updates, apply them one by one over the next hour? In these circulmstances CIS has a backlog to clear, so there will be a performance hit. Please edit your post to add this clarification.

Do CIS ever cause a failure to resume from hibernation?

Best wishes


hi mouse1,

I have updated my post as requested.

Thanks for a very thorough bug report.

Moving to format verified


I have this problem too, but without hibernation
till last day that I’ve updated my V DB, this problem occurred.
exactly the cmdagent.exe uses 116 Mb of RAM.
I re-installed Comodo, but after the update of V DB, the problem have been returned, again.
