Openconnect GnuTLS error

Hello dear friends, I setup an openconnect server and was working perfectly for 2 days, however today it doesn't connect and the futex facility gave me these error :

Dear friends, do you know the source of this problem that just started happening by itself, is it a hack ? is it because the server I rented doesn't have enough capacity ? I am the only user using it.
