Large cmddata file
« on: August 11, 2017, 03:40:37 AM »
In the ProgramData folder. A file from comodo takes up 35 GB of valuable space on my SSD. I only found this russian topic on the problem.
https://forums.comodo.com/10551086108810911089108910821080-russian/--cmddata-129--t120172.0.html;msg863527

The solution they mention, is reinstalling. Which is what I'll be doing right now. I just want to report it, so it's know this bug appears more than once.

[EDIT]
After reinstalling, they file size has reduced to 98 MBytes.

[EDIT2]
A. THE BUG
Can you reproduce the problem & if so how reliably?:
No
One or two sentences explaining what actually happened:
The file cmddata located in "C:\ProgramData\Comodo\Cis\lmdb" has grown to 36GB over time.
One or two sentences explaining what you expected to happen:
The file size should have remained around 98 MBytes
Any other information, eg your guess at the cause, how you tried to fix it etc:
Probably caused by not clean installing updates.

B. YOUR SETUP
Exact CIS version & configuration:
10.0.1.6258 (Pro Active Config)
Modules enabled & level. D+/HIPS, Autosandbox/BBlocker, Firewall, & AV:
Antivirus, Stateful
Auto Contain, Enabled
HIPS, Safe Mode
Virusscope, Enabled
Website Filtering, Enabled
Firewall, Safe Mode
Have you made any other changes to the default config? (egs here.):
Apart from application specific rules, no.
Have you updated (without uninstall) from CIS 5, 6 or 7?:
Yes
     if so, have you tried a a a clean reinstall - if not please do?:
     Yes, this fixed the problem. For now

OS version, SP, 32/64 bit, UAC setting, account type, V.Machine used:
Win10 Pro, 64-bit.

Do you maybe remember which version you updated to v10?
Did you experience this issue with previous version(s)?

The same issue was described in the Russian section on July 19.

I've updated from 8.5 to 9 and to 10. I am pretty sure I have not reinstalled between 9 and 10. I might have between 8.5 and 9.

Hi All,

The Comodo Firewall is installed on my PC (Win10x64).

The cmddata file in the C:\ProgramData\Comodo\Cis\lmdb\ directory is 49.8GB (!!!)

What's the file is? Should it be so big? How to reduce its size?

Thank you!

So, how to fix? Just to delete this file? I cannot - only SYSTEM can modify this file....

What data should be kept in this file? Probably it's related to the system restore/backup?

Is it safe to delete it (if I find a way to do so)?

How to solve? This file should not be so big, it takes about 1/4 of my SSD...

One thing I would like to see is the stats of the database, download the attachment from this post and after unzipping double click enable_page.reg, then alt-click on any file or folder and select JSON: dump statistics of the database and attach it here. Also state what version of CIS you have installed and how do you update to newer versions of CIS, e.g. do you run the internal updater or do you download and run the installers such as the online web installer or the offline installer.?

Mine was also 48 Gb. But I have a hybrid HDD, so this is not depending on the disk type.
I fixed it in other way: just unload Comodo from the memory and tried to stop remaining service by attempt to kill it through the Task Manager. Of course it can't be killed, but it seems it released that file so I could delete them. Now after the launching Comodo again I have the file about 96 Mb too.
So there's no need to insert your HDD or SSD to the other PC.

Hi!
This is my first post, so please do let me know if I'm posting it in the wrong place.
I have CIS version 12.0.0.6818 running on my computer for over a year now, and I suddenly noticed that a file called cmddata.lmdb has reached the size of 134.1Gb! I researched the topic and read that this file shouldn't exceed 1Gb tops for any reason. I wonder, can I just delete this file and let CIS create again, hopefully in a smaller size? What do you think is the best course of action here?

Thanks ahead.

You can delete it. It should not grow so big.
