If cmddata file would grow to another excessive size you can delete is as a workaround.

Using 12.2.2.7036 my cmddata file size is currently at 2.677GB.

Note, I also use Killswitch to show untrusted images in memory.

V12.2.2.7036 (Firewall only) on Windows 7 Ultimate 64-bit

Mine C:\ProgramData\Comodo\Cis\lmdb\cmddata is currently 98Mb and seems to be steady.

What is actually stored in this file?

As a test: What do I have to do in CIS or on the system to let it grow in size? (Not that I want to have a bigger file :) )?

After renaming it in safe mode, mine is again back to 98MB also.

Good question, I'm not entirely sure what causes it to go crazy in file size.

I'd like to know too!

Back up to 196MB after a Windows update.

Hello ReeceN & aim4it,

As per CIS team,If they reduce the file size in the sense it will affect some of the CIS components,So the better solution is you can delete the file if the size exceeds.Further if you need any clarification don't hesitate to ping us.
Have a nice day!

Kind Regards,
PD

I've checked my file again, it's now at 100Mb.

Also I've checked the content of the file (the bytes it contains).
It seems that approx. 94 % of the file is just zero bytes, so only 6 % is non-zero bytes.

If CIS needs all these zero bytes maybe it should compress this file in a clever way to reduce the (in my opinion) redundant zero bytes.


Edit :

When the file size, as reported by some, goes up to (or over) 1Gb and the ratio 94/6 (% zero/non-zero bytes) is still valid then this is really a waste of disk space (even if we have Tera bytes HD space these days).
Please think of compressing the data in this file.

Sorry Dharshu, I'm with CISfan on this one.

Considering how the file size increases from 200mb - 1GB is a short space of time (days), without really doing much, I have little reason to believe that this is working efficiently.

Clearly something is wrong.

Furthermore removing a file in safe mode is not a very user friendly method of maintaining your security software either.

I'd rather the issue be fixed instead of providing a work around.

I have tried uninstalling (including with the removal tool) and reinstalling and after the 2nd day it is back up to 196MB.

Each time the file increases in size, the general performance of Windows actually slows down.

It is the slow down that first alerts me to tell when the file has likely increased in size.

Furthermore overall RAM usage also increases as the file gets larger also.

I think a solutions for this would be highly beneficial, especially to those who require good performance from their computer.

Currently back at 393MB.

It's been there for a while. Maybe that's its happy number.
