The value needs to be increased to a value that fits with the day to day activities of the environment in question, a good base value for this is to set it to 10 levels as this will allow a reasonable amount of file nesting within containers.
It is good to know that the reason for the container limit is primarily to stop attacks such as a "zip of death" or "zip bomb" denial of service type attacks.
The log entry which appears should be similar to the following:
A container violation has been found
