OPENSSL_internal:invalid library

[fabiodemartin]

Hi,

I installed openlitespeed-1.8.2-1.el9.x86_64 on AlmaLinux 9. After enabling debug mode for the logs, I noticed a large number of the following entries:

2024-12-10 13:24:34.811695 [DEBUG] [51633] [189.29.183.147:57799:HTTP2] H2ConnBase::onReadEx2 read(2495) return 0

Is this behavior normal, or could it indicate a missing library? Do I need to make any adjustments to resolve this?

It is normal, all zero means no error, maybe should avoid logging that line.
