3402002 - Performance issue between ABAP and HANA caused by Third Party Tool

You are facing many ABAP work processes waiting for HANA Database.

For example: As per ST12 trace you see long running SQL Statements, however on HANA DB SQL PlanCache the Performance is good.

Creating a C-Stack in transaction SM50 as per SAP Note: 2733232 - PROC memory consumption included in StackTrace information

for one affected Work process is showing following or similar C-Stack:
