Litespeed cache module stopped working today out of nowhere

[the.rampage.rado]

As I was pumping products in my shop suddently I started seeing 500 in FO on many pages.

Then I tried deleting htaccess - no success. Tried deleting my litespeed cache and system cache and started seeing 500 on all FO pages.

Googling the issue I stumbled on https://github.com/litespeedtech/lscache_prestashop/issues/44

I'm running my shop on php7.4 and it was not changed. I'm unable to run higher php because my theme is not compatible and also my slider poops everywhere.

Any advise what could be causing this sudden issue?

The error log from the server:

Added  ctry in the bypass section as per the advise in github and now it appears to work as expected.

Will monitor it further.

Do we have this issue in TB: https://github.com/PrestaShop/PrestaShop/pull/23269/files as it's described in the issue thread above?

This is nice bug. Calling __destruct on connection instance make this instance unusable, but does not remove it from connection pool.

Sequence like this would fail:

Db::getInstance(_PS_USE_SQL_SLAVE_)->__destruct();
Db::getInstance(_PS_USE_SQL_SLAVE_)->execute('select * from table');
