Solved LogBlock-Connection-Pool freezes console

Hi!
I have a problem with LogBlock. I didn't observe any specific reason nor time, when this error occurs, it's pretty random. When this warning appears, it freezes console ie. I can't enter any command and nothing can be displayed below that warning. Console just stops. BUT, the server itself still works fine. Everyone can connect, play and LogBlock in-game works as always. /reload doesn't help, I've to restart the whole server to use the console again.

Here's the console message:
[08:41:45] [LogBlock-Connection-Pool housekeeper/WARN]: LogBlock-Connection-Pool - Thread starvation or clock leap detected (housekeeper delta=5m27s390ms296?s924ns).

MC version: 1.16.4
LogBlock version: 1.15.1

How to fix it? What can cause it? Do you have any ideas?

Thanks in advance for answer!

EDIT:
Found solution! But still, I have no idea, what exactly caused it.
I used a plugin "ConsoleSpamFix" to block above warning from the console. No message? No freezed console!
