When McAfee Agent restores database files, it causes a port conflict with some third-party applications

Technical Articles ID: KB94871
Last Modified: 2/11/2022

Environment

McAfee Agent (MA) 5.7.0 - 5.7.4, 5.6.x

Supported Linux operating systems

For environment information, see KB51573 - Supported platforms for McAfee Agent 5.x.

Problem

When you restart the Linux server, the McAfee Agent performs a database integrity check before the services start. This action can cause a conflict if a third-party product is listening to the McAfee Agent wakeup port. The default port used is 8081, even if you’re using custom ports.

NOTE: A third-party product can't bind to the port because the McAfee Agent is using it. The McAfee Agent updates its custom port on every ASCI, which frees the port.

You see errors similar to the following in the maconfig.log file:

maconfig.Info: database file <mascheduler.db> is empty.Needs to be restored the MA DB
maconfig.Error: MA databases integrity check failed = (2)
maconfig.Info: restore backed up configuration file </var/McAfee/agent/db/ma.db.config> to </var/McAfee/agent/db/ma.db>.

Workaround

Edit two files and disable ma_check_and_restore:

Access the Linux system.
Open both files listed below with a text editor, such as vi.
- /opt/McAfee/agent/scripts/ma
- /etc/init.d/ma
From within both the scripts, search for ma_check_and_restore, and comment out ma_check_and_restore.

NOTE: The commands are located after the start() function.

Example:

Before:

start() {
# MA common services start
echo ""

if [ ! -d /var/McAfee/.msgbus ]
then
mkdir /var/McAfee/.msgbus
chmod 777 /var/McAfee/.msgbus
chmod o+t /var/McAfee/.msgbus
fi

if [ $PPID -eq 1 ]
then
echo "MA services are started by init process"
ma_check_and_restore
fi

After

Save the changes.
