CF10: Address already in use: JVM_Bind

After a fresh install of CF 10 multiserver I have made 6 instances.

After a reboot of the server 4 of the instances have an exception:

"Address already in use: JVM_Bind"

java.net.BindException: Address already in use: JVM_Bind

All the features and applications seem to work. But I'm not convinced.

Can someone please help me?
