Drayden Posted March 14, 2021 ID:1444619 Share Posted March 14, 2021 Title pretty much says it all. My system just crawled to a halt and had to reboot, but right before I did I noticed my RAM usage was at 31GB. After the reboot, I opened up task manager and Malwarebytes was using 15GB and within a minute or two it was over 20GB and still climbing. There was no scan or anything taking place. Is there anything obvious that might be causing this? I've had to turn the program off to avoid it from using all my RAM again. Thanks in advance 1 Link to post Share on other sites More sharing options...

wyang Posted March 14, 2021 ID:1444621 Share Posted March 14, 2021 I just had the same problem, I noticed that a lot of my apps had crashed all at once for no reason, and my fans were going at max speed. I checked the task manager and malwarebytes service was using around 95% of my ram. I tried ending the task multiple ways and it always just gave a message saying access denied. It was so bad that my computer ended up going to a black screen twice and I ended up just uninstalling malwarebytes to make it stop. I have no idea what could of caused this problem. Possibly a bad update? Link to post Share on other sites More sharing options...

Hoofbites Posted March 14, 2021 ID:1444626 Share Posted March 14, 2021 I'm seeing this as well. mbst-grab-results.zip Link to post Share on other sites More sharing options...
Sparkoson Posted March 14, 2021 ID:1444627 Share Posted March 14, 2021 I reinstalled. Seems fixed but I'm assuming those 2 minutes without MWB is exactly what the hackers needed... Link to post Share on other sites More sharing options...

Please do the following Uninstall and reinstall using the Malwarebytes Support Tool Please have lots of patience with the tool. The first phase is a cleanup and does require a Windows Restart. After the Restart, it may take 2 - 3 - 4 minutes till the Support tool screen shows up. Please be patient and have faith. Wait for it, whatever it takes. The 2nd phase is where it offers to do a new Install. Then follow the instructions in this topic after the clean install and before you do your first scan.

Not sure if there's anything useful in these logs still since I uninstalled/reinstalled, but here they are: mbst-grab-results.zip Link to post Share on other sites More sharing options...

We really could have used the logs before the reinstall. Keep an eye on it though. I also see an issue with Windows Defender as well. Link to post Share on other sites More sharing options...
xriv Posted March 14, 2021 ID:1444643 Share Posted March 14, 2021 Also having the same issue. Restarted computer and monitored Memory usage on idle/startup, the ram usage for client just continued to climb didn't seem to stop (no scan) Link to post Share on other sites More sharing options...
Darkdirk Posted March 14, 2021 ID:1444647 Share Posted March 14, 2021 I had the exact same thing happen as well. I've been freaking out for the past two hours thinking it was a malware attack. Now seeing so many others with this same problem, I'm thinking it's probably a bad MBAM update. When I browsed to my MBAMService\logs folder, every single one of my MBAMSERVICE.LOG files (MBAMSERVICE.LOG.bk1, MBAMSERVICE.LOG.bk2, etc...) were completely filled (10MB each) within the past 30 min. Can anyone else browse to their logs and see if they have the same situation? Link to post Share on other sites More sharing options...
MJL Posted March 14, 2021 ID:1444651 Share Posted March 14, 2021 Mine were also filled up but the time in the date modified field was today at 1:19am which was when the first of many entries started in the event log warning of a low virtual memory condition. I did notice in General Tab of MWB Settings that the option to collect enhanced event log data for support (not recommended) was selected. I don't ever recall turning that on. I checked 2 other systems and they did not have the option checked and did not seem to be exhibiting any high memory usage problems. All 3 systems are running Version 4.3.0.98 with update package 1.0.38137. The 2 unaffected systems are running Component package version 1.0.1173 whereas the affected system is running version 1.0.1217. I turned that event log option off to see if that helps Link to post Share on other sites More sharing options...

Could you check your logs folder (located at c:\ProgramData\MalwareBytes\MBAMService\logs), and tell me if you have a bunch of MBAMSERVICE.LOG files that we all modified today?

Erix Posted March 14, 2021 ID:1444653 Share Posted March 14, 2021 Ladies and gentlemen, We know about this problem now and can tell it will happen when a scan is scheduled to the time of Daylight Savings adjusting. The work around for it is to delete all scheduled tasks, restart MBAM (or reboot machine) and create a new scheduled scan. We are working on a fix for this and will post as soon as we have it ready for release. Thank you so much for your patience, -Erix 1 Link to post Share on other sites More sharing options...

This might be a big ask, but can you confirm for me if this is why every one of my MBAMSERVICE.LOG files were all completely filled with mostly: DEBUG TaskScheduler mb::common::misc::ScheduledTask::MyTimerAPCProc "taskscheduler.cpp" DEBUG TaskScheduler mb::common::misc::ScheduledTask::Schedule "taskscheduler.cpp" DEBUG TaskScheduler mb::common::misc::ScheduledTask::MyTimerAPCProc "taskscheduler.cpp" DEBUG TaskScheduler mb::common::misc::ScheduledTask::Schedule "taskscheduler.cpp" DEBUG TaskScheduler mb::common::misc::ScheduledTask::MyTimerAPCProc "taskscheduler.cpp" DEBUG TaskScheduler mb::common::misc::ScheduledTask::Schedule "taskscheduler.cpp" over and over and over?

orubio Posted March 14, 2021 ID:1444679 Share Posted March 14, 2021 (edited) Apologies for the hassle, definitely a bug on our end. Our engineering team is aware! Reboot will take care of it :) We appreciate your patience Edited March 14, 2021 by orubio 1 Link to post Share on other sites More sharing options...
Staff Solution ChuckOp Posted March 14, 2021 Staff Solution ID:1444682 Share Posted March 14, 2021 Malwarebytes Service restart should be sufficient. Bug is made worse due to DEBUG logging being enabled, which causes the excessive logging and memory consumption. It's a bug that got out and we will fix it and ensure it does not happen again. 3 Link to post Share on other sites More sharing options...
