Have seen this also on different 1.4 versions (1.4.18), created a bug
report and was told this to be a DNS issue. I do not think it is, but
never got this one fully solved.

'This bug is surely a DNS related problem, if you look over /main/dns.c
you'll find:
"Asterisk DNS is synchronus at this time. This means that if your DNS
does not work properly, Asterisk might not start properly or a channel
may lock."
Try to change nameservers in /etc/resolv.conf.'

What distribution & kernel are you using?

That I didn't notice, had to do a reboot (!).
