Then something is fishy here, since you are showing version 6.3.3000.111 here, but your AX AOS crash event log entry says a higher version:

Faulting application name: Ax32Serv.exe, version: 6.3.5000.5032

You must make sure kernel version matches, otherwise it will cause a lot of issues! Communication protocols are regularly adjusted between patch versions, which can cause unreliable behavior and crashes.

Again, same instructions: patch it all up, delete cache files, and if it still crashes, collect a crash dump and open a support incident.

You seem to be using an older kernel, the latest one is not older than 2 weeks, this would be the first thing Microsoft would suggest as well.

blogs.msdn.microsoft.com/.../overview-of-microsoft-dynamics-ax-build-numbers

Make sure you patch up all AX components, you are not allowed to use different client and server executables and assemblies..

Do you have enough resources? I have seen AOS crashes when memory was too low, and due to a memory leak in a customization or in the kernel it went kaboom due to eating up all resources. Our deployment has 180 concurrent users, split between 2 AOS instances, which has 8 physical CPU cores and 32 GB RAM (+4 additional AOSes for batch/reporting/AIF integrations).

Finally, you could collect a crash dump using the Windows Error Reporting (WER) tool by setting a registry key to capture a first-chance exception, then open a Microsoft Support Incident and upload it to the support team to check what exact code call causes the crash.

There are 100 license,three AOS loadbalancing enviorment,but concurrent users go 180 .

Concurrent user is alaways more than no of license customer has purchased.
