Out of Memory Error

[Hacker]

I have invoked the MRT by pressing Ctrl-M. The MRT window showed up and this error dialog on top of it:

EOutOfMemory means that TC was running out of memory. The call was
getmem(result,2*sectsize+2);

[Hacker]

Christian,
Um, well, OK, does that help you or me in any way? Any steps to troubleshoot next time this happens perhaps? Any steps to avoid this happening again?

Christian,
Scrolling in a dir with ~80 000 files, then pressing Ctrl-PageUp while the list was still being scrolled. Brief view, one file color filter active.

Same problem - it seems that you have some kind of memory leak. When you get this error, can you check with task manager how much memory is used by TC? Just do NOT close the error dialog first.

[Hacker]

Christian,
Working Set Private was a bit below 200 MB in both cases. Should I check any other value in Process Explorer in case it happens again?

Thanks
Roman

[ghisler(Author)]

No, you can't see this - it may be the total number of allocated Dephi objects, not the overall memory. How long does TC run until you get this? A few hours? A few days?

[Hacker]

Christian,
Usually just a few hours, say around 6. Certainly not a full day.

That's odd, I'm usually running TC for multiple days (the PC only goes to sleep mode, no reboot). Are you doing anything unusual which could be eating a lot of memory?

[Hacker]

Christian,
Well, my computer is pretty strained, lots of processes running, lots of tabs open in Firefox etc., but the physical memory usage rarely exceeds 75% of available memory (6 GB out of 8 GB).
What I have noticed, though I am not sure if it is relevant in any way, TC first starts reacting very slowly. When I then close it (by clicking X as usual) and restart, it does not restore the previous tabs / dirs even though it is configured to do so and normally does, so basically in these cases it does save the current state to the wincmd.ini upon closing.
I have a feeling it might be connected either to Bitdefender, XnView (as sometimes this happens after invoking [and returning from] Thumbnail view) or a combination thereof. Just a hunch, though.

Are you able to save the settings manually before closing via menu Configuration - Save settings?

[Hacker]

Christian,

Are you able to save the settings manually before closing via menu Configuration - Save settings?

I just tried. TC got slow, I clicked Configuration - Save Settings, got no error message, closed TC, started TC and the previous directories were not restored.

Roman

[ghisler(Author)]

Sounds like TC is gettings slow due to the out of memory situation, and the ini functions also start to fail...

[Hacker]

Christian,
Usually TC takes up ~15 MB "WS Private" as shown in Process Explorer, before it freezes it takes up between 100 - 200 MB. So, I agree with you, something is wrong with the memory usage, however I always have at least 2 GB physical memory free, even when TC freezes.
Is there anything we can do about it?

TIA
Roman

Maybe you can check in Windows task manager what is causing the memory to grow that much? Try all functions involving third party extensions which you use regularly like:
- context menu
- properties (Alt+Enter)
- any plugins you use
