I'll spare you of the details here, because I already have a lenghty thread here with many logs:

I also have an e-mail reply from Zora where she explains a few bits and possible causes:
Hi Hyper,
the only details that it gives to me is:
Why would a function try to allocate 20,474,369 bytes when it needs to load a file of only 14,890,427 bytes? That's 5,583,942 bytes too much! Since it's not a power of 2 or anything else which rings a bell the only conclusion left is that this function is buggy. Maybe in a next Nephthys version Nephthys will do that by itself instead of using an existing function.
However, I don't think that would solve your problem:
1. I assume that your system has enough (virtual and physical) memory in the moment of the memory request
2. The amount of memory requested is small compared to your system specs
3. Your Unreal server ran out of memory before it ran Nephthys web support (you can disable web support for verifying this and I'm sure your server will still crash with "out of vm" as it did before)
4. Even if the exact size isn't reasonable to me it still has to work
The only reason left imo is: The unreal internal memory structure is corrupted or even your system's memory structure. That's why requests fail after a while.
Small requests don't fail because there's some blocks allocated from the system but marked as free inside the unreal process. Small requests will be solved by those fragments. For large requests (as loading the file for checksum or computing the UPackageMap as your crashes before) a request to the system has to be made which fails due to structure corruption.
If not the entire system is compromised in those cases, it sounds to me as if the system's memory structure for only that unreal process is corrupted. This can be caused by native functions which allocated a certain size of memory but use a large size and overwrite the system's structure informations thereby. This can be caused by any native library (including Nephthys, but also others, like render dlls) but it even can be caused by the game itself (unreal.exe).
If you're interested in tracking down the cause of your problem and can't live with a crash every few weeks you should use "divide and conquer":
Run your server without as many native mods as possible and look if it still happens.
If yes, these excluded mods weren't the cause. Try to eliminate more mods then.
If it doesn't crash any more, include half of the mods again and try again (etc. etc.).
That way you should be able to determine the causing mod.
But since I neither can look into all native functions nor I have any insights into Window's memory management this is all only assumptions :p
