How do I completely disable jailshell and get rid of /home/virtfs

[hostultra]

cpanel keeps mounting filesystems inside /home/virtfs which is causing my server to crash.

Analyzing the dumps show the crash is occurring during a file system mount.

Since I dont mount anything after the server boots, i can only conclude that this jailshell is causing it.

I do not allow any SSH access to my server, so there is no need for jailshell and virtfs, so how do I get rid of it?

[sirotex]

cPanel only mounts when you enable Jailshell on an account. Assuming you've probably ticked the option in Tweak settings 'Use jailshell as the default shell for all new accounts and modified accounts' then untick it.

"Use jailshell as the default shell for all new accounts and modified accounts" is unticked.

And it definitely mounts when ssh is disabled for accounts.
Running df shows this:

Change the shell to /bin/false. The noshell allows SFTP logins, which may be causing this.
