Description

We are using Derby Network Server in DataPower appliance. Underlying OS is a Linux based. Derby Server is accessed only by java processes running on the same appliance. We are noticing that the Derby server process is running into OutOfMemoryErrors. Post the OOM errors, connection requests to the server are failing and the CPU usage reaches 100%. We are also noticing deadlocks reported in the logs. Please help identify the cause and how the issue can be resolved.
