Application which uses MuleSoft SMB Connector, throws error "Not enough credits (0 available) to hand out 1 sequence numbers"

SYMPTOM

Mule Application throws errors and warnings with these or similar messages:
 

Not-enough-credits-0-available-to-hand-out-1-sequence-numbers

There are no credits left to send SMB2_SESSION_SETUP, will block until there are more credits available

CAUSE

This issue relates to SMB Protocol credits available on the target system that the connector is attempting to connect to. The administrator of that system has not allocated enough SMB Protocol credits to allow the incoming connections.
 

SOLUTION

Contact the System Administrator for the service that you are trying to connect to using SMB Protocol. They will need to increase the credits to support the number of connections coming into their system.
