Bamboo Limit Concurrent Builds Across Branches

Does that help There are outstanding feature requests for this BAM-12071 and BAM-2423 waiting on Atlassian to implement a solution.
In the meantime we devised a quick and dirty workaround for this based on using old fashioned file (actually directory) locking. Each resource is defined with a variable name gatekeeper.resource in the job or branch configuration, At the beginning of a build process a "Gatekeeper" stage checks that the required resource is free using a directory name in a common file on a common server. While the directory name exists the resource is in use. The first task of the subsequent build stage creates the resource name as an empty directory, and a final task removes it. Other builds cannot proceed past the first stage until the resource is free, stopping concurrent builds. The downside is that it does tie up a local bamboo agent, and is not completely foolproof but does work for us 99% of the time. It even works across build plans if the resource variable is defined correctly.
# This Gatekeeper stage prevents concurrent builds against a resource 
# by looking for a directory instance in a common file area.
# If the directory exists the build cannot proceed until it disappears.
# The build sleeps as long as the directory exists.
#
# The first task in the subsequent stage is to create the directory, and 
# a final task in the build removes it.
# As a failsafe a background half-hourly cron job should remove lock 
# dirs if they exceed 3 x the build time.
#########################################################
# Wait for a random number of seconds 20-120 to reduce (but not eliminate) the chance that multiple competing branch
# builds triggered by timers both see the dir gone and start the unit test job at once and then proceed to clobber each other (i.e a race condition)
# note: bamboo expects output every 3 minutes so do not increase beyond 180 seconds
SLEEPYTIME=$(( ( RANDOM % 100 ) + 20 ))
echo SLEEPYTIME today is $SLEEPYTIME
sleep $SLEEPYTIME
# Wait for the Gatekeeper lock dir to disappear... or be older than 3 hours (previous build may have hung)
file=/test/atlassian/bamboo-gatekeeper/inuse-${bamboo.gatekeeper.resource}
while [ -d "$file" ]
do
  echo $(date +%H:%M:%S) waiting $SLEEPYTIME seconds...
  sleep $SLEEPYTIME
done
exit 0
# This will fail if the lock file (actually a directory!) already exists
file=/test/atlassian/bamboo-gatekeeper/inuse-${bamboo.gatekeeper.resource}
mkdir "$file"
file=/test/atlassian/bamboo-gatekeeper/inuse-${bamboo.gatekeeper.resource}
rm -rf "$file"
# This works in conjunction with bamboo unit tests. It clears any unit test lock files after 3 hours (e.g. build has hung or killed without removing lock file)
15,45 * * * * find /test/atlassian/bamboo-gatekeeper -name inuse* -mmin +180 -delete

How to limit Jenkins concurrent multibranch pipeline builds?

hope this fix your issue Found what I was looking for. You can limit the concurrent builds using the following block in your Jenkinsfile.
node {
  // This limits build concurrency to 1 per branch
  properties([disableConcurrentBuilds()])

  //do stuff
  ...
}
pipeline {
    options {
        disableConcurrentBuilds()
    }
}

How to limit concurrent matrix/multi-configuration builds in Jenkins

like below fixes the issue I think you have to use a matrix job to trigger the builds of a separate job doing the real build. Then you can use the Throttle Concurrent Builds Plugin to limit the number of parallel executions of that job you start by the matrix.
