Action Cable processes getting killed when last session connection closes before "unsubscribe" finishes

[AhmedWaleedAhmed]

Technologies used:
ruby '2.7.0', rails '5.2.5', passenger '5.3.2', devise '4.8', redis '4.0'

When passenger process in a shutdown mode and we have our last session this session dies when we have a big transaction like (5 sec) in the unsubscribe method to be done after the session is dead we will face an issue which is passenger won't wait till this transaction ends it will kill it and roll back the transaction so the logic in unsubscribe method won't be done which can cause unwanted behaviors in future especially if it's related to information must be committed in the database to use it in future.
