On some systems, executing many discovery or visibility jobs at once can cause CDV to exceed a system's limits on the number of connections. To avoid this, CDV manages discovery processes in a queue, limiting the number of simultaneous jobs to a default of 20.
Tip: Within the Visibility tab for a particular infrastructure, jobs that are
waiting the queue have a status of "pending": 
To change the default number of jobs, set the parameter MAX_PROCESS_SIZE
when deploying the CDV container. For example:
docker run -d \
-p 80:8000 \
-p 443:44300 \
-v <volume-name>:/var/lib/postgresql/ \
-e BAM_IP=<your_bam_ip_address> \
-e MAX_PROCESS_SIZE=10 \
--name <gateway_container_name> \
