Defect ID	Headline
CSCvu44472	FMC System processes are starting

Problem Description

Some versions of Firepower Management Center (FMC) software might cause the security management platform to halt unexpectedly.

Background

Some versions of FMC software might cause the security management platform to halt unexpectedly. The Sybase database becomes unresponsive, which causes the issue.

Problem Symptom

The FMC appliance halts and indicates "System processes are starting" over the console port.

When you switch to expert mode in the CLI, this message is displayed:

You have logged in while system startup is in progress. Please wait, some feature may be unavailable until startup is complete.

The web-based GUI shows this message:

The server response was not understood. Please contact support.

The Sybase database located in /var/opt/CSCOpx/MDC/log/operation/sydb.out will contain logs similar to these with timestamps that match the onset of the issue.
