I get this error quite a bit. It doesn't cause any real problems though. [2006/07/03 13:13:13, 1] libsmb/ntlmssp.c:ntlmssp_update(267) got NTLMSSP command 3, expected 1 this is what worries me. 26 in queue but according to my reporting there were only 22 people accessing the proxy between 1 and 2. 2006/07/03 13:17:24| WARNING: All ntlmauthenticator processes are busy. 2006/07/03 13:17:24| WARNING: up to 5 pending requests queued 2006/07/03 13:17:37| storeDirWriteCleanLogs: Starting... 2006/07/03 13:17:37| WARNING: Closing open FD 8 2006/07/03 13:17:37| Finished.

We plan on putting over 300 people on this proxy in a week and a half. This has happened twice and squid has always restarted in 3 seconds. A 3 second hiccup multiple times in a day would be a problem. The access log doesn't show anything helpful and there's nothing in squid.out. Any help would be appreciated. Thank you.
