I have aspnet core application and I create V8 isolate object for each request and dispose end of the request. Sometimes I am seeing
FatalProcessOutOfMemory exceptions even though I have enough available physical memory (RAM). Is there any heap limitation for V8 ?

AllocateRawOrFail(int size=-2133860350, ...) looks bad. Apparently that request is coming out of the snapshot...

Hello Jakob,
The only possible way to size (int size=-2133860350, ...)was negative if there is int overflow. I am not using any external snapshot blob during V8 isolate object creation which means V8 is using DefaultSnapshotBlob data. I thought every time I create V8 isolate object, it'll initialize from DefaultSnapshotBlob data and size is 1047264. Would you give me some inside knowledge how snapshot is used during isolate object creation if there is no external snapshot provided? Do you think should I use an external snapshot object to initialize isolate object?
Thank you
Siam

Using the default snapshot should be fine, and it should definitely not be >2GiB in size. Something is weird there. I'd suggest investigating in more depth (with a Debug build) where that negative size is coming from.
