Components Upgrade 1.0.1689 causing possible Memory Leak?


Recommended Posts

Ever since the upgrade to Components version 1.0.1689 with the latest 4.5.9.198, my computer seems to have developed a memory leak that I have never had before.

** I am being blocked by the spam filter for some reason, how can it be turned off? as I have 2 paragraphs to post **

    • Clean: Performs an automated uninstallation of all Malwarebytes products installed to the computer and prompts to install the latest version of Malwarebytes for Windows afterwards. The Premium license key is backed up and reinstated. All user configurations and other data are removed. This process requires a reboot.
    •  Repair System: Includes various system-related repairs in case a Windows service is not functioning correctly that Malwarebytes for Windows is dependent on. It is not recommended to use any Repair System options unless instructed by a Malwarebytes Support agent.
    • Anonymously help the community by providing usage and threat statistics: Unchecking this option will prevent Malwarebytes Support Tool from sending anonymous telemetry data on usage of the program.

Is there anyone else having an issue? I don't necessarily need support as yet because I want to try run some diagnostics and tests of my own, but just interested if anyone has noticed anything. The only other software change I had made on my PC around the same time was upgrading Brave browser to the latest version (about 1-2 days beforehand). I had noticed nothing unusual until perhaps 6 hours after installing the components upgrade however. I only realized there was an issue because my Brave browser started crashing with very little tabs open after certain amounts of time. Using Youtube would speed this along. I do not have a lot of ram on the windows 10 machine (only 4GB). I also do not use a swap file which clearly doesnt help.

As an aside, is there a tool available to verify the integrity of a Malwarebytes installation? **spam blocker stops me from continuing this comment**

I am also facing a situation similar to this poster:
https://forums.malwarebytes.com/topic/286137-questions-about-certain-log-entries/

Malwarebytes is absolutely spamming fresh MBAMSERVICE.LOG files filled with thousands of these lines. 10MB every 12 minutes, churning up my drive! Could this be a cause of a memory leak?

Regards!

Thank you for your reply Porthos! At the minute I am not looking for support quite yet, I want to have a tinker first and see what I can find. If this is the incorrect forum for a general enquiry of the forum users please move it to the appropriate section much appreciated. I hope I am not wasting anyones time. I had more to explain but the spam filter is catching me :)

To be honest,you are in the correct place since you suspect the component update to be an issue.

The requested logs will help us assist you in tracking down the issue.

Hi Porthos,

I seem to have found the issue:

When I am using my PC I have a batch script running constantly that looks at services that should not be running and ends them. It uses the "net stop" command as well as the "timeout" command, which actually happen to be executables (they can be found in system32: net.exe, net1.exe, timeout.exe). So anyway this script is very fast, and fires these commands out perhaps 20-30 in 1.5 seconds AKA it is opening these executables and closing them instantly as needed. Once I slowed this script down to only fire every 30 seconds (instead of 3), the  memory leak issue stopped.

Now I believe the issue is with the Log files that Malwarebytes creates. I noticed in: C:\ProgramData\Malwarebytes\MBAMService\LOGS the MBAMSERVICE.LOG file (which is moved to MBAMSERVICE.LOG.bk1, bk2, etc as it hits 10MB in size) was being hammered with new lines that matched the ones in this thread: 

These log files would fill up within 10 minutes. My assumption is that Malwarebytes was trying to attach itself to the net.exe, net1.exe and timeout.exe's but they were closing too fast hence the errors. Once I slowed my script down to only fire every 30 seconds, the errors drastically reduced (or at least were not being written as fast). So in conclusion there is probably a link between the log files and memory leaking. There is probably still leaking but it should no longer affect me because I have reduced the scripts speed by 10x (it generally takes me a good 4 hours before I will be at 90%+ memory usage, with all apps closed).

This is most certainly an edge case so I will leave this matter up to you and the Malwarebytes team whether they want to look into it.

Regards

Hi onebyteboi:

Just FYI, I checked my C:\ProgramData\Malwarebytes\MBAMService\LOGS folder and I currently have 10 MBAMSERVICE.LOG backups (i.e., with a .bk1, .bk2, etc. extension) dating back to 24-Apr-2022 and each is just over 10 MB in size.  It appears to be taking about 3 to 4 days for my MBAMSERVICE.LOG to reach it's max size and create a new backup.

The oldest backup, MBAMSERVICE.LOG.bk10, contains entries dating back to 20-Apr-2022.  I don't know if it's a coincidence but 20-Apr-2022 is the same day I upgraded from Malwarebytes v4.5.7.186-1.0.1645 to Malwarebytes v4.5.8.191-1.0.1666.  Once my current MBAMSERVICE.LOG reaches 10 MB I don't know if it will create a new MBAMSERVICE.LOG.bk11 file (i.e., if these backup files will continue to accumulate) or if the the oldest backup will be deleted to make room for a newer backup.

I've attached my oldest MBAMSERVICE.LOG.bk10 backup file (zipped) that includes log entries dating from 20-Apr-2022 to 24-Apr-2022 as well as diagnostic logs gathered with the Malwarebytes Support Tool.

Hi onebyteboi:

Hi Imacri,

These logs are normal and yes the 10th is deleted as a new one is created. Either a coincidence or the version you stated was when they were introducted. The fact yours span back to April is a good thing at least. Mine are full of errors because of the behavior of my batch script and I go through them like butter. My assumption is there to be a link between this mass of errors (in my case) and memory leakage. My situation is very edge case and fixable on my end so I am not too bothered if it is deemed low priority.

Hi onebyteyboi:

Good to know that the number of MBAMSERVICE.LOG backups (i.e., with a .bk1, .bk2, etc. extension) shouldn't increase beyond ten files and eat up my available disk space.  I wonder if logging in MBAMSERVICE.LOG has become more verbose (i.e., if additional types of errors are being logged) since Component Package v1.0.1689 was released on 26-May-2022?

What is your definition of a memory leak?  Do you mean that the amount of RAM consumed by a Mawlarebytes process like MBAMService.exe or mbamtray.exe continues to grow steadily over time after every re-boot, and that additional memory used by one or more of these processes is not released (i.e., returned to the pool of available memory) after a Malwarebytes background task has finished running?

Note that user unknownguy recently reported seeing unusually high network activity in their 15-May-2022 thread Latest Stable Release Send Too Many Requests, which has since been moved to the Windows Malware Removal Help & Support board for one-on-one troubleshooting.  I have no idea if their issue is related in any way to your "memory leak", but it would be helpful if you could post Malwarebytes Support Tool diagnostic logs as previously requested.  These logs can only be viewed by Forum Administrators and users with advanced permissions.

Hi onebyteyboi:

Hi Imacri,

It is not any process that is growing in memory but the entire amount above and beyond what is tabled in processes. The amount is reset after reboot. I suspect it is possibly the Malwarebytes driver and not one of the .exe processes OR the Malwarebytes software is causing leaks in my aforementioned net.exe, net1.exe, timeout.exe causing them to reserve RAM without releasing it back when they close out (I don't know if this is how RAM works but I have heard something like it before; that a process can be closed but it's RAM reservations can stay?). I will look at this tool you listed.

An update on this RE latest version (4.5.10.200):

Latest version seems to have fixed this issue, although I have not kept my computer online for a decent length yet to make sure (I will let you know if anything changes). I am no longer seeing the "kernel" lines in the logfiles anymore.

Regards
