Each shared resource has an allocation of locks which can be acquired and held by builds or stages. This These locks are allocated at server or agent level.
Server Shared Resource locks can be acquired while evaluating configuration conditions and also while selecting an agent. Any builds which that require Server Shared Resource locks, which are held by other builds, will wait on the build queue or stage queue until the required locks are released.
Agent Shared Resource locks are allocated per agent and can be acquired when an agent is selected for a stage. Continua CI will chose the agent with the highest available allocation of the required locks. If there are no Agent Shared Resource locks available for any available agent, the build will wait on the stage queue until the required locks are released.
