Camunda took long time to deploy

Dear All,
We recently ran into an issue that it takes long time (40+ min) to deploy our process app that consists of one master process and 7 sub-processes. My question is what maybe the cause for that? what’s remedy or even workaround for this issue?

Here is the log excerpt that we observed:

The above block repeated N times until it finally deployed.

Camunda version: 7.3
OS: Alpine 3.12
Spring boot app

Thank you so much for the help.
