How do I get the distribution of application memory in Windbg #62626

Open hueifeng opened 2 years ago

hueifeng commented 2 years ago

In address -summary, I found inside MEM_COMMIT to 4.423 GB, but I can only get in eeheap 405618688 bytes, I passed! Heap -s can get the memory is very small.Memory. Now I don't know, how can I investigate the remaining memory of MEM COMMIT .

How can I see how these memory spilled?Usually I can use! Heap -s to see the disclosure issues of Windows NT, but I can't see it in this.

!address -summary MEM_COMMIT 4.423 GB

Issue Details
In address -summary, I found inside MEM_COMMIT to 4.423 GB, but I can only get in eeheap 405618688 bytes, I passed! Heap -s can get the memory is very small.Memory. Now I don't know, how can I investigate the remaining memory of MEM COMMIT . How can I see how these memory spilled?Usually I can use! Heap -s to see the disclosure issues of Windows NT, but I can't see it in this. !address -summary MEM_COMMIT 4.423 GB ``` 0:000> !address -summary --- Usage Summary ---------------- RgnCount ----------- Total Size -------- %ofBusy %ofTotal Free 579 7df9`74541000 ( 125.974 TB) 98.42% 912 206`7c9dc000 ( 2.025 TB) 99.99% 1.58% Image 972 0`06a01000 ( 106.004 MB) 0.00% 0.00% Heap 81 0`05a27000 ( 90.152 MB) 0.00% 0.00% Stack 114 0`02a80000 ( 42.500 MB) 0.00% 0.00% Other 9 0`001de000 ( 1.867 MB) 0.00% 0.00% TEB 38 0`0004c000 ( 304.000 kB) 0.00% 0.00% PEB 1 0`00001000 ( 4.000 kB) 0.00% 0.00% --- Type Summary (for busy) ------ RgnCount ----------- Total Size -------- %ofBusy %ofTotal MEM_MAPPED 220 200`062b0000 ( 2.000 TB) 98.74% 1.56% MEM_PRIVATE 935 6`7edfe000 ( 25.982 GB) 1.25% 0.02% MEM_IMAGE 972 0`06a01000 ( 106.004 MB) 0.00% 0.00% --- State Summary ---------------- RgnCount ----------- Total Size -------- %ofBusy %ofTotal MEM_FREE 579 7df9`74541000 ( 125.974 TB) 98.42% MEM_RESERVE 296 205`709f6000 ( 2.021 TB) 99.79% 1.58% MEM_COMMIT 1831 1`1b0b9000 ( 4.423 GB) 0.21% 0.00% --- Protect Summary (for commit) - RgnCount ----------- Total Size -------- %ofBusy %ofTotal PAGE_READWRITE 862 1`0e1cc000 ( 4.221 GB) 0.20% 0.00% PAGE_READONLY 579 0`0659a000 ( 101.602 MB) 0.00% 0.00% PAGE_EXECUTE_READ 159 0`04f2b000 ( 79.168 MB) 0.00% 0.00% PAGE_NOACCESS 80 0`01550000 ( 21.312 MB) 0.00% 0.00% PAGE_EXECUTE_READWRITE 19 0`002ba000 ( 2.727 MB) 0.00% 0.00% PAGE_WRITECOPY 94 0`001aa000 ( 1.664 MB) 0.00% 0.00% PAGE_READWRITE | PAGE_GUARD 38 0`00074000 ( 464.000 kB) 0.00% 0.00% --- Largest Region by Usage ----------- Base Address -------- Region Size ---------- Free 21e`6c05c000 7bd5`f48f4000 ( 123.836 TB) 7dfd`d8ac0000 1f7`68898000 ( 1.966 TB) Image 7ff9`71121000 0`009ba000 ( 9.727 MB) Heap 218`83c71000 0`00eff000 ( 14.996 MB) Stack 22`cad80000 0`0017c000 ( 1.484 MB) Other 218`f1b50000 0`00181000 ( 1.504 MB) TEB 22`ca410000 0`00002000 ( 8.000 kB) PEB 22`ca40f000 0`00001000 ( 4.000 kB) ``` !eeheap -gc 405618688 bytes. ``` 0:000> !eeheap -gc Number of GC Heaps: 12 ------------------------------ Heap 0 (00000218F3182A40) generation 0 starts at 0x00000218F34C9DB0 generation 1 starts at 0x00000218F3477478 generation 2 starts at 0x00000218F3461000 ephemeral segment allocation context: none segment begin allocated committed allocated size committed size 00000218F3460000 00000218F3461000 00000218F3A0BDC8 00000218F3F02000 0x5aadc8(5942728) 0xaa1000(11145216) Large object heap starts at 0x0000021BF3461000 segment begin allocated committed allocated size committed size 0000021BF3460000 0000021BF3461000 0000021BF449E8D0 0000021BF44BF000 0x103d8d0(17029328) 0x105e000(17162240) Pinned object heap starts at 0x0000021CB3461000 0000021CB3460000 0000021CB3461000 0000021CB3464FF0 0000021CB3472000 0x3ff0(16368) 0x11000(69632) Allocated Heap Size: Size: 0x15ec688 (22988424) bytes.

You could try !address without the -summary flag to figure out what the individual pieces of commits are. Trying your repro locally, I could find quite a bit of module images and mapped files.

You can also try !eeheap without the -gc option to see what other heaps the CLR internally uses.

I don't quite understand if my application is calling virtualAlloc, but its physical memory is very high.

image

Run this Program, access to http://localhost:5000/excel, you can find that its memory has been growing, this is actually because there is no timely dispose .

For now, I'm using !finalizequeue to see, but I don't understand if I go through Windbg to check memory problems, for the program's problems can not be found in visible memory?

do you have any update on this issue?

do you have any update on this issue?

No, I am not actively working on this issue, is our suggestion above works for you?

You could try !address without the -summary flag to figure out what the individual pieces of commits are. Trying your repro locally, I could find quite a bit of module images and mapped files.

You can also try !eeheap without the -gc option to see what other heaps the CLR internally uses.

Beside that, we have a new !maddress command built by @leculver, feel free to try that one as well.

@tommcdon, can this issue be closed?
