Why does Sphinx swear at template code?

Question

1C-Bitrix

There was a server failure. After that, a number of configs flew off, including Sphinx stopped working. When I set it up, there seemed to be no problems, I copied the typical config and everything started up.
Now it won't start and throws an error:

[[email protected] ~]# systemctl start sphinx
Job for searchd.service failed because the control process exited with error code. See "systemctl status searchd.service" and "journalctl -xe" for details.

FATAL: failed to open log file '/var/log/sphinxsearch/searchd.log': No such file or directory

Make sure the /var/log/sphinxsearch/ directory exists.
