After I followed recommendation from postg= res group and upgraded PG r15 to r16, I did somewhere miss that MIT-krb5 distinguishes FQDN and shortname, and some of my applications did hammer th= e DB with futile logins. Then I got backtraces straight from gethostbyaddr() into malloc(): https://forums.freebsd.org/threads/trouble-bus-errors-and-segfaults-in-libc= -so-from-postgres.101876/post-750679 I cannot perfectly align that security update. It was built and deployed on= Jan 31, but the server was rebooted into -p8 on Feb 2 16:05, while the first cr= ash happened on Feb 2 03:52. It is unclear when exactly the binaries on that respective jail have been replaced. --=20 You are receiving this mail because: You are the assignee for the bug.=
