| Summary | 0000002: Crash when using site finder on large worlds (mem usage >2gb) | ||||
| Description | When using the site finder on a 257x257 world, the memory consumption rises constantly and when it reaches 2 GiB, DF crashes. I suspect this is because there is no virtual memory left. | ||||
| Steps To Reproduce | 1. Create a 257x257 map 2. Start playing, Fortress Mode, Use the site finder, search 3. Watch memory usage climb 4. crash | ||||

The crash @2GB is expected. 32bit windows applications have a 4GB memory space, but only 2GB can be used (the other 2GB is reserved for system use [think stack, etc]). If you're on a 32bit platform, booting with /3GB will move you from a 2GB/2GB process space split to a 3GB/1GB split. This may be enough to work around the crash, as it seems to be close to completing the search -- but I cannot test that now to confirm. If this is not a memory leak, df.exe either needs to be optimized to use less memory or recompiled to be a 64bit executable. (The 64bit recompile would be nice however :) ) |

I know that. While it is correct behavior for the application to terminate when its address space is used up, DF should not use that much memory. And using /3GB is not a solution because there are enough applications and drivers that crash and burn when used with it. |
|
|
Confirmed. The site finder works fine in 40d, but in 0.31.01 it takes FAR longer, and then crashes (for me after around an hour at 200ish/257). |
|
|
I can confirm this as well. However it's slightly different for me. Just as my memory is filled (2GB, Win7 32 bit) Windows gives me a runtime error: "This program has requested the runtime to terminate it in an unusual way." |
|
|
I can confirm, though I forgot to check the Memory usage. Odd considering I'm on a 64-bit system, but I guess 32bit emulation will still crash if it gets to high. (I have 8 GB of memory) |
|
|
Confirmed on 64-bit system (Win7 Ultimate). See also http://www.bay12games.com/dwarves/mantisbt/view.php?id=136, for when you reduce the overall map size just enough to make the finder not crash. |

This should be handled for 0.31.04. |
