[Koha] "rabbitmq-server" post-installation script

Dear list members, Due to a discrepancy in the size of the actual space used (the database contains just over half a million records and the database dump is approximately 4GB) compared to the expected size, an attempt was made to find out exactly where the additional 350GB was located. To assist in this process, it was decided to use the "ncdu" program. However, when the "sudo apt install ncdu" command was executed, there was an unforeseen problem with the execution of the "rabbitmq-server" post-installation script, and it switched from "started" to "starting" mode (output is in the attachment). Could you please explain the reason for this problem and provide instructions on how to fix it? Thank you in advance. Sincerely, Aram
