I've been having the same problem but it hasn't been as bad as yours. Every once in awhile I'll see the R(reserved) flag. I was told to check the connection to the Active Directory. Whatever it is it sounds like a Samba issue. I get the same issue with the invalid sid string format too. If you figure this out please let me know.

Hi!! We have two squid proxies running at our site, both of them with the same versions and configurations (Fedora Core 5, Samba 3.0.22-1.fc5, installed through rpm, and Squid 2.5.STABLE13. Both are running on Dell servers with the same configuration. Samba on both machines is configured with "security = ads", and the testes "wbinfo -t", "wbinfo -u" and "wbinfo -g" all runs ok. One of them is running just fine, but the other is crashing every day, due to ntlm authentication problems. The only difference is that the proxy that is running ok is installed with 64 bits version of Fedora, and the other one is running with the 32 bits version. Squid´s compile options are the following: configure options: --enable-auth=ntlm,basic --enable-delay-pools --enable-snmp --enable-useragent-log --prefix=/usr/local/squid --enable-ssl --enable-underscores --enable-storeio=ufs,aufs,diskd --enable-external-acl-helpers=wbinfo_group The problem we are facing is that ntlm helpers begin to enter in "R" and "B" states, until every one of them stops authenticating, and then Squid dies. The error message associated to the crash is this: " Too many queued ntlmauthenticator requests (301 on 60)". During all day, we get the following message as well: " string_to_sid: Sid S-0-0 is not in a valid format." Does anybody know what could be the problem, or how could we trace it? Wich one should be the best squid´s debug_level for this problem? Thanks in Advance, André PS: By the way, not related to this question, how do you users of Gmail can send messages to the list? I always try, but even with the option for sending messages not in HTML format chosen, i can't send messages to the list. If anyone has a hint about this also, it would be very appreciated.
