NEW hidden conf MAIN_DISABLE_DNS_GET_RECORD
On some servers, for reasons unknown, the PHP function
dns_get_record()gets completely unresponsive and blocks the whole apache server while waiting for a DNS resolution until it eventually times out.We tried to troubleshoot the issue (by trying to call the function from a php cli, by comparing with other DNS tools like
resolveipordig, by modifying/etc/resolv.conf, etc) but we did not find a reliable solution yet, so the hidden conf solution can be helpful for cases like this.
