Why does MySQL crash during Bitrix installation?

Question

MySQL

MySQL crashes during installation, it no longer starts with the current database, if you remove the database, then MySQL rises, but the installation does not go "main module installation error", Centos 7 with BitrixENV is installed on the hosting.
Hosting hc.ru, several times already reinstalled the OS and started the installation on a new one, each time it crashes at the same place (Installing the "Online Store" module (DB data) ...).
At the same time, the installation on a local machine in VirtualBox proceeds normally, the transfer of the backup of an already installed portal to the hosting does not work on restoring the database - MySQL server has gone away
Manual filling of the database in MySQL - gives ERROR 1030 (HY000) at line 18723: Got error 168 from storage engine
Bitrix technical support answered "contact hosting"

Answer 1

That's right - this is not a Bitrix error, but a server error.
There are several ways to get "ERROR 1030 (HY000) at line 18723: Got error 168 from storage engine".
The most common:
1) Not enough space on the hosting (Hosting is greedy and gave you only 2GB for Bitrix, and it is recommended for a clean installation of at least 10GB)
2) You ran into the number of simultaneously open files.
In any case, only the DBMS log can give an exact error.
