Seems like a
bug with myhost dhcpd parsing itw own time comments. I reverted back
to ‘db-time-format
local’ and after the second restart (to clear up the file after
writing)
all seems well again. Is this a known bug or an issue on my end? I’ve
seen
this in at least (2) different versions of 4 including 4.1.1 running on
Redhat
5 (2.6.18-164.9.1.el5) using failover.<o:p></o:p></p>

Hi,<br>
<br>
Couple days ago I submitted to <a class="moz-txt-link-abbreviated" href="mailto:dhcp-bugs@isc.org">dhcp-bugs@isc.org</a> a patch for this
problem with this comment:<br>
" Since 4.0.0 common/parse.c::parse_date()
<br>
has been renamed to parse_date_core()
<br>
and new parse_date() function has been created
<br>
as a wrapper around parse_date_core()
<br>
to consume the semicolon after the date.
<br>
However parse_date_core() has not been properly
<br>
updated and still tries to consume semicolon on it's own
<br>
with parse_semi() or skip_to_semi().
"<br>
<br>
The ticket has been assigned an ID of [ISC-Bugs #21501].<br>
<br>
I'm attaching the patch also here for the case that you are interested.
