High memory used WPHB_cache_preload

Hi there,

I’m having such a big memory consumption. The server says that this error below is the cause. What could be happening?

[Thu Aug 06 10:50:54.905924 2020] [:error] [pid 1619:tid 47186274453248] (12)Cannot allocate memory: [client 172.69.34.154:39412] couldn’t create child process: /usr/sbin/suphp for /home/musi5819/musicaymercado.org/wp-admin/admin-ajax.php, referer: https://www.musicaymercado.org/wp-admin/admin-ajax.php?action=wphb_cache_preload&nonce=08ecf2b93b

all my best regards,
