Are there mount limits for jailshell on Virtuozzo?
Quoted from the cPanel documentation:
CentOS 6 and older support a maximum of only 256 jailshell users on a system that uses the Apache mod_ruid2 module. If you encounter this limit, you should consider an upgrade to a newer operating system.
Some customers have reported performance and connection issues when they attempt to mount more than 4000 targets in a Virtuozzo environment. If you encounter this limit and still require a large number of jailshelled users, you should consider a different virtualization platform.
