OrientDB shutting down

Products

• CA Test Data Manager (Data Finder / Grid Tools)

Issue/Introduction

F&R models are not getting displayed in portal and getting error as "Internal server_problem Error in creating or accessing the database". We have checked in backend and found that orientdb service is getting stopped after 2 -3 mins . We have analyzed the OrientDB logs and found the below error but we have minimum 25 GB free disk space.

Environment

4.10.x

Cause

Checked and found that there is a MS SQL Server Database instance running on the same machine and it was consuming 90% of the total RAM(128 GB).

Resolution

Restart the SQL Server service which will release the RAM memory and OrientDB service will be able to start fine and F&R models would work fine from Portal UI.

As a prevention, check with a DBA and limit the consumption of MAX RAM by SQL Server instance.
