GUI Lockup lsass

[AntKnee]

The issue I have been having is that xyplorer locks up randomly and for various intervals (usually seconds, but could be about 1 mintue sometimes. I found that it is directly correlated to the windows process "lsass.exe" running at the same time. Or rather the lsass.exe process using cpu cycles. I have spent time looking into this process. I can't kill it or windows crashes. It seems to be related to logon security, but there isn't anything/anyone logging in to the computer. It also seems to only affect xyplorer. Windows explorer and all other programs never lock up. Has anyone else ever had this? Is there anything that can be done about this?

I am running windows 7 64-bit.
This is the second computer to have the same issue-which is why I am surprised no one else experinced this.

It drives me mad to be locked out of accessing the files for a few seconds here and there (espiceally when you need to do something).

This seems to have always happened in varying degrees and not related to just the newest version of xyplorer.


Thank you,

Thank you,

In order to exclude two known problems:
1. You don't have a file operation (copy/move/delete) going on when this happens?
2. Are XYplorer.exe and XYcopy.exe excluded from real-time scanning in your security software, particularly if you're running MS Security Essentials or the built-in Windows Defender?

I do appreciate that the CPU usage you describe as related doesn't exactly fit either, but it helps to eliminate the obvious.

I'm also on Win 7 x64 - and have experienced sporadic "not responding" hangups. I'll be interested to see what Don has to say about this.

To answer your questions nas8e9:
1-I don't have an opretaion running when this happens. Just leaving the computer idle it will happen.
2-I don't run any anti-virus software at all. and windows defender doesn't run real-time.

I also wanted to note how/why it is easy to be noticed. I use ultramon (software for multiple displays). Whene ever a program is locked, its 2 icons for moving the window (which are next to the minimize/close) appear black and shifted slightly. The window is then locked-this is standard as any program that hangs appears the same way. I ave attached 2 images showing the difference.

I'm not sure we are saying the same thing about the cpu cycles of lsass. I mean't that everytime xyplorer locksup i notice it happens exactly as lsass.exe is using some cpu cycles. In case anyone else has similar lockup they can check to see if it also is happening when lsass is being used.

Thanks far any help as this would be a huge fix as i have been dealing with ths for some time.

2-I don't run any anti-virus software at all. and windows defender doesn't run real-time.

At the risk of flogging a dead horse, does completely disabling Windows Defender (Tools > Options > Administrator > Use this program) make any difference?

As far as the CPU usage of LSASS.exe is concerned, you observe *some* CPU usage. I don't know how many cores your processor has, but if more than one, could you check with Task Manager or Process Explorer whether a particular core is heavily used (say, > 50%) by LSASS.exe? On a hyper-threaded quad core, I rarely see more than 10% total CPU usage even when one core is heavily used, which to my mind can mask things.
The reason I ask is that LSASS.exe showing high CPU usage is, politely put, a rich and varied problem. From your description though, only XYplorer seems to suffer?

Finally, since LSASS handles login security, do you have any network file shares which require login?

[AntKnee]

Well, I tried disabling defender as you mentioned, but it still occurs.

As for the cpu usage of lsass, it is always less the 10%. I do run on an x4 it the process is only one core. It does not seem to lockup xy because of cpu consumption. maybe something it is doing?

For the network, i don't have an login/share that would check every minuete or two. at least not that i know of. i do run on a cable ethernet (not wireless), so i ruled out wireless card bad and therefore checking/auth.

Thanks for your help in tracking this. Any thoughts Don ?

[AntKnee]

Still frustrating as ever...today seems extra 'sensitive' as i am locked from doing even the simpliest things. i even have to resort to windews explorer!

As for an update:
1-I tried to just unplug my network connection to see if that makes any difference. NONE. Still locks up.
2-I did find something interesting: as i mentioned today seems extra lockup, meaning lsass.exe is running extra long and therefore locking me out. durring this time i was able to try a few things to see if it makes a difference. what i found seems to be that this lsass.exe lockup is related to xyplorer specifically. meaning maybe xy is doing something to cause it to check authority or something and then freeze. basically what i did was kill xyplorer in an attempt to restart it and see if i can use it with less locks. what i noticed is that when i killed xy, lsass stopped as well. i tried a few times and got the same result. hopefully this can shed some light into why this is happening.

any word on this?

any word on this?

I have never seen this issue. No explanation strikes my mind.

[AntKnee]

I am very disappointed. Is there anyway of tracking this down? What am I supposed to do? It makes the product unusable!

In another (constant) attempt to fix this, I uninstalled my copy. I downloaded the latest and installed it. So now I have a fresh copy. GUESS WHAT? STILL HAPPENS!!

It seems to get worse and worse the longer th compute is on and useduse (i'm guessing without a restart).


...The constant lag when dragging files (which sometimes doesn't work because it is hung). The constant waiting to have to access a file. TOTAL FRUSTRATION!!!

I have the issue that looks the same as described by AntKnee. I have a fresh installation of latest (not beta) XYPlorer on my Windows 7 x64. Some strange GUI lockups occures sometimes. It looks like XYPlorer window becomes absolutely unresponsive. After some time it is possible to move a window with insane lags - window jumps over the screen when i try to move it with a mouse.

My theory was - the usage of MS Security Essentials, because in my case the lockups appear to happen only at first launch of XYPlorer. I tried to uninstall the MS SE and using Avira for now. Will look further on this issue, but currently no more lockups.

Yes, this theory was already put forward by nas8e9 on 10 Mar 2011 13:21 . Let us know please how it works.

[AntKnee]

I can tell you I have already tested everything nas8e9 mentioned.
I don't run Any anti-virus. I unistalled MS Security Essentials.

Still Random Lockups.

I'm also on Win 7 x64 - and have experienced sporadic "not responding" hangups. I'll be interested to see what Don has to say about this.

I too am on Win 7 x64 and after some troubleshooting I found that the cause of my "not responding" hangups (which seemed to get more frequent and worse) was a particular setting. It is the "Show icon overlays" setting on the Advanced setting of Configuration. I use three programs which use Icon overlays and turning this off solved my hangups permanently. I would rather than the overlays on but can live without them. Does that help either of the other OPs?

You weren't able to determine which of the three was the worst offender?
