Interesting. What did you do right before "suddenly" actually?
Nothing, or something and somewhere? :o)

It seems that you have some nontrivial DNS configuration? Some local
daemon like named or unbound? Could you show us some example?

ping some.server # what ip is used here? what says tcpdump port domain?
grep some.server /etc/hosts # or is the translation from hosts?
grep hosts /etc/nsswitch.conf # do you have "hosts: files dns" here?
cat /etc/resolv.conf # something suspicious here?
ldd -a /usr/local/bin/bacula-dir | grep libc.so # just /lib/libc.so.7 here?
file /usr/local/bin/bacula-dir # for which FreeBSD is it compiled?

Ping uses gethostbyname2(). Bacula uses getaddrinfo(), if there is
#define HAVE_GETADDRINFO 1 in src/config.h. So ping and bacula could
behave differently, but it is weird. Unfortunately, nslookup and host
use different mechanisms. They skip /etc/hosts for example. So they
can check remote DNS server, but not problems with local translation,
which seems to be your case.

And please how?

Could you do gdb bconsole and check, that timeout is with name resolution?

And looking into bacula-7.0.5 sources, I think that debug level 100
and tracing on should be sufficient for tracing name resolution
(src/lib/bsock.c and BSOCK::open, then bnet_host2ipaddrs and resolv_host
in bnet.c).
