Why Does the Number of Concurrent Sessions Reach the Limit When I Use CBH to Log In to a Host Resource?

Symptom

There is a limit on the number of concurrent SSH connections established between CBH and servers it manages. If this limit is reached, no more users can log in to CBH unless a logged-in user logs out.

Possible Causes

There is a limit on how many concurrent connections can be established between CBH and a managed host resource. If multiple users establish concurrent connections to a host resource over SSH, a user will be logged out once the number of concurrent connections reaches the limit.

Solutions

CBH supports multiple asset specifications. The number of concurrent connections varies depending on the asset specifications.

To fix this issue, change your CBH instance specifications to increase the concurrent request quota.
