On a linux ubuntu 8.04 server with squid 3.0.STABLE1 and samba 3.0.28a
configured to authenticate against a windows 2003 server active
directory with samba winbind ntlm-auth, the ntlm-auth processes keep
slowly getting locked in "RESERVED" state until squid emits the error
"Too many queued ntlmauthenticator requests" and restarts.
Is this the expected behavior of squid?
Below it's an output of cachemanager3.cgi:
