[squid-users] Squid crash, what happened?

We use Squid with samba for NTLM authentication. Last night I started to see a few entries here and there , then they started to show more and more:

[2006/04/05 21:29:56, 3] utils/ntlm_auth.c:winbind_pw_check(427)
  Login for user [domainname]\[username]@[computername] failed due to [No logon servers]
[2006/04/05 21:30:05, 3] libsmb/ntlmssp.c:debug_ntlmssp_flags(62)
  Got NTLMSSP neg_flags=0xa208b207

Then eventually I got this:

2006/04/05 21:30:52| WARNING: up to 30 pending requests queued

And finally:

It then kept repeating the following for about 8 cycles then stopped:

This morning I got my alert and restarted and it worked fine. It appears it could not find a domain control or as the log states a DNS server. I cant see why, I have no record of it being down. Can anyone make light of this situation, or is it safe to assume that squid just couldn't see a DC/DNS and gave up.
