We were even able to reproduce the issue without Veeam in the picture, by creating a test tool that does nothing except bombing SQL Server with large queries from multiple threads.This tool has also consumed all available system memory very fast and produced a crash dump that is identical to ones submitted by our customers. After uninstalling the update, memory consumption of the test tool remains steady at 26-28MB.
Microsoft has been notified.
