I am trying to create a replica using pg_basebackup and every time it gets stuck at a random percentage (80 to 96) percentage. The primary is looping in the getting "recvfrom(10, 0x7ffe06388c27, 1, 0, NULL, NULL) = -1 EAGAIN (Resource temporarily unavailable)" and the Secondary just loops and gets "Timeout". What can be issued? I checked the system resources (like FD, number of processes by Postgres user, etc), and everything looks fine. Is there any clue we can extract from strace? I don't see any logs or errors in /var/log/postgresql/postgresql-15-main.log. We are using PSQL psql (PostgreSQL) 15.3 (Ubuntu 15.3-1.pgdg18.04+1).
Could you please give me a pointer about it how to solve this problem?
