There are a lot of script code in the application, so it is difficult to find the specific lines of code that causes the crash. Does anyone have any ideas what could cause that or advice how to debug this issue?
Comments: Thanks! You are right, it was a memory limit issue. I think Docker has some default memory constraint for the container. After I specified 2GB memory for the container the application runs fine.

Comments: We've posted a potential fix [here](https://clearscript.codeplex.com/SourceControl/changeset/1db6dbc9d458ec5fafa15d5574a0e2709a1b220d). Since we haven't been able to reproduce the issue, it would be great if you could give it a try. As the fix is relative to ClearScript 5.4.9, you might pick up some performance improvements as well. Good luck, and thanks again!

Comments: An access violation inside native V8 initialization nearly always indicates an out-of-memory condition. When it fails to allocate resources, V8 immediately crashes the process by raising an access violation. At startup, a V8 runtime tries to acquire large amounts of memory and address space to be handed off to its internal resource manager. Any allocation failure leads to an immediate crash. Does your crash always happen _after_ a recycle? Or can it happen randomly at any time? Other questions: Does your application run in a 32-bit process? Is it possible that it creates a large number of V8 runtimes? Does it specify memory limits via `V8RuntimeConstraints`?
