XF 2.1 Session problem

[Eagle]

I really don't know what this situation is about but there's a very interesting thing going on. We're having a problem with the session. User sessions truncating automatic. What would cause automatic reset/truncate with xf_session's table per hour? For example members: 52, guests: 367 total: 419 but after 1 hour, resetting and starts again. What could be the problem?

I think I've found the problem. Today I found that phpredis does not work with PHP 7.3. So I mean phpredis extension is not officially compatible with PHP 7.3. Anyway. To solve problems, just disable phpredis.
