Help me figure it out, Apache lays down steadily once a day :( But maybe more often. I don’t understand what it can cause. On VDS, one website is spinning. It can go up to 100 online. But at the same time, Apache lives and turns as it should. At night when there isn’t load, something smashes it.
In the logs here is such information.

Immediately after restarting Apache, this error falls out:

    For posterity: The reason was in Xcache. Disconnected it and the problem disappeared.
