Hello,
i have encountered a strange behaviour with a firebird server 3.02 on debian (9 strech) in superserver mode : the server has shutdown without any reason (no human). in fb log i can see that : Wed Mar 21 18:01:12 2018 Shutting down the server with 736 active connection(s) to 91 database(s), 0 active service(s) Wed Mar 21 18:01:16 2018 /usr/sbin/fbguard: /usr/sbin/firebird normal shutdown. the last log say that is a normal shutdown but i don't see why (noting in other linux log). what are the possible case for a normal shutdown ? An other thing strange is that fbguard doesn't restart the fbserver (GuardianOption = 1 in firebird.conf) someone have an idea about what could have happened ?
